DeepMind, an AI analysis laboratory based in London in 2010, was acquired by Google in 2014. In April 2023, it merged with the Google Mind division to grow to be Google DeepMind.
John Flynn, often generally known as ‘4’, has been DeepMind’s VP of safety since Might 2024. Earlier than then he had been a CISO with Amazon, CISO at Uber, director of data safety at Fb, and (between 2005 and 2011) supervisor of the safety operations workforce at Google.
What made him concentrate on a profession in cybersecurity? Cybersecurity wasn’t a standard occupation when he graduated, however two life experiences had converged.
First, he was “obsessive about computer systems from an early age.” He received his first laptop when he was 13. “I might spend all day and all night time hacking on stuff, instructing myself to code, and making an attempt to solder issues onto my laptop to make it play the most recent recreation that was past its native energy.”

Second, he grew up in violent places. He talked about he had lived in Nairobi (Kenya had comparatively not too long ago achieved independence from Britain following terrorist exercise led by the Mau Mau); Liberia (which suffered two civil wars between 1989 and 2003); and Sri Lanka (civil warfare between the Sinhalese majority and the ‘Tamil Tigers’ from 1983 to 2009). Extra particularly, he remembers tear gasoline within the playground and his college getting burned down.
Bodily safety was at a premium for the younger Flynn. “That and my obsession with computer systems progressively targeted my curiosity on cybersecurity.” He went on to realize a grasp’s diploma in laptop science.
It’s shocking what number of of in the present day’s safety leaders first discovered about cybersecurity via childhood recreation hacking. This raises a query – ought to a safety chief be a hacker at coronary heart? It needs to be mentioned that there are lots of opinions on what makes a hacker – see the separate Hacker Conversations for examples – however Flynn replied, “If you happen to say {that a} hacker is someone who likes to discover and check the bounds of recent applied sciences, then the reply is ‘sure’.”
He expanded, “My private model of CISO is a really technical one with an engineering background, and that skillset mixed with testing limits permits me to bridge the danger aspect of the equation with the intentions of the builders. It helps us discover novel options to addressing threat whereas enabling clients and staff to do what they should do.”
How, then, did this engineering technologist with a hacker’s mindset find yourself with one of many world’s main synthetic intelligence analysis organizations? “It’s actually fairly easy,” he mentioned. “I’ve all the time needed to assist individuals with what I do.”Commercial. Scroll to proceed studying.
It’s maybe value noting that earlier than he began his cybersecurity profession, he was a Peace Corps Volunteer and nonetheless lists well being and human rights amongst his pursuits.
“It’s fairly straightforward to really feel that working in cybersecurity can profit your employer, nevertheless it’s much less straightforward to search out and really feel that what you do is a profit to humanity at giant.” Some years in the past, he acknowledged a fledgling AI was unfolding its wings and would profit, or not less than have an effect on, all of society and never simply companies.
“That is a very powerful know-how that’s been launched to humanity in a very long time, and there are lots of questions on the right way to make it safe and protected. I felt I wanted to be a part of it – to attempt to assist with that course of; and I really feel like DeepMind is the one finest place on the earth to try this. DeepMind isn’t merely making an attempt to invent the way forward for AI, however to take action in a means that may assist and empower humanity in a protected method. I simply needed to drop every little thing and do it.”
He’s actually speaking much less about what we have now now (gen-AI and agentic AI) however extra concerning the subsequent massive step: synthetic basic intelligence, or AGI. That is synthetic intelligence with the flexibility to know, study, and apply intelligence throughout totally different domains. It’s going to successfully be proactive AI the place we’re presently restricted to reactive AI. And that will likely be a complete new ball recreation in an area the place humanity has but to know the social, psychological and financial results of what we have already got with gen-AI.
We puzzled, given his curiosity in human rights, whether or not he noticed any battle between human rights and synthetic intelligence. “I don’t know that I can touch upon any battle,” he mentioned, “however I believe the vital level is that AGI know-how is coming. Many individuals are engaged on that. And if I can do my bit to shepherd the know-how of the long run in a means that’s as protected as attainable, I believe I’ll be ok with my contribution.”
On condition that present AI nonetheless makes errors, we might be remiss if we missed this chance to problem a senior officer from a significant AI analysis group as regards to AI errors. The widespread reply is that some errors are inevitable since gen-AI is basically a probabilistic engine – it replies with what it believes to be in all probability probably the most appropriate response.
However the very existence of ‘likelihood’ has been questioned. Chance entails randomness; it’s God enjoying cube with outcomes. In a distinct however related context Einstein successfully mentioned God doesn’t play cube. The underlying suggestion is that likelihood is a time period utilized to determinism we don’t (maybe but) perceive.
It’s an vital however unresolved query, as a result of it implies that the likelihood in Ai that results in its errors might be resolved if we understood the determinism underlying the likelihood: if we all know precisely why an error is made, we might stop a repetition sooner or later.
That is the query we put to Flynn: are we disguising our inadequate understanding of how AI works by ‘dismissing’ it as a likelihood machine?
“I believe I might say probabilistic is an apt description,” he replied. “That description places it apart in relation to historic cybersecurity which is arguably extra deterministic than the novel challenges we face with AI. For instance, you can provide the identical immediate to the identical AI and get two totally different solutions. That occurs fairly regularly with the way in which AI works. Probabilistic is a simple approach to perceive this phenomenon. It additionally lends itself to alternative ways of fascinated by protection towards assaults – so I might say that probabilistic is a good description.”
Flynn makes use of the phrase probabilistic to distinguish AI purposes from conventional and extra clearly deterministic basic laptop purposes. However an alternate means of trying on the concern could be to outline AI outputs as ‘chaotic’ (from chaos principle). Chaos principle means that advanced and dynamic programs are deterministic however unpredictable making AI unpredictable somewhat than probabilistic. It’s a gorgeous concept because it comprises the chance that if we perceive the impact of all of the variables that make up the system, we might doubtlessly predict and in the end enhance the accuracy of AI. A second implication from chaos principle is that that is unlikely to occur.
An open query in the present day is whether or not the arrival of AI is altering the position of the fashionable CISO. Cybersecurity initially emerged as a separate self-discipline from info know-how – and early CISOs tended to be technologists and engineers. The self-discipline itself carried its historical past within the authentic title: ITsecurity.
As malicious threats grew in quantity and complexity, the necessity for separate cybersecurity experience turned obvious; nevertheless it was nonetheless largely grounded in IT. The threats, nonetheless, have been quickly turning into ‘entire of enterprise’ threats somewhat than merely threats to laptop programs. No a part of the enterprise could be untouched by cybersecurity, which in flip pressured CISOs to know enterprise priorities.
So CISOs have been pressured to increase their experience and grow to be businesspeople in addition to technologists. ‘Businessperson’, nonetheless, is a simplistic summation. To combine know-how and safety throughout the entire enterprise, CISOs additionally should be psychologists. They should perceive enterprise leaders and staff (and be capable to discuss coherently to each); to know how and the place attackers may strike, predict how workers may react to work restrictions in workflows, and be sufficiently subtle to get what they want from the board with out dropping their job.
So, the fashionable CISO should be each technologist (engineer) and a psychologist (enterprise). Will this modification once more with the arrival of AI. Does in the present day’s CISO now additionally should be a scientist?
Flynn is a technologist by tutorial coaching (laptop science) and accepts the position of psychology. Internally it’s a vital trait for all leaders, and externally it’s helpful in monitoring adversaries. However he doesn’t contemplate himself to be a scientist though the position more and more entails science. “I don’t attempt to fake to be one myself, however I’ve scientists on my workforce.”
As for the science of AI, he mentioned, “I had grow to be so obsessed with AI during the last a number of years that I obsessively taught myself, a lot of it on the aspect. I discovered that coming into DeepMind, there was extra studying to do, however a yr on from beginning within the position, I really feel snug each on the safety aspect and on the analysis aspect.”
The CISO could not should be a scientist, however a scientific mindset needs to be added to know-how and psychology – and what’s lacking on the outset should be discovered on the job. That is considerably confirmed by what he considers to be a very powerful persona attribute for a CISO.
“Humility is the very first thing that involves thoughts,” he replied. “In safety, and particularly in AI safety, we have to deal with a number of unknowns, and we’re nonetheless working our means via among the options as a society. I’ve seen many leaders in safety the place hubris will get in the way in which of seeing what’s and what isn’t an excellent resolution to an issue. I believe humility is a vital coaching in all leaders – and particularly in safety.”
Humility appears to be a pure a part of Flynn, maybe partly on account of surviving a surprisingly harmful youth. However recommendation obtained from mentors within the progress of a profession can be vital.
“Most likely the perfect recommendation I ever obtained is that this,” he mentioned: “The position of a frontrunner is admittedly two issues, Firstly, to rent the perfect individuals on the earth; and secondly, to verify they’ve the proper context to do their jobs successfully. If you happen to do these two issues, a number of issues are solved or prevented.”
Too typically he has seen solely the primary half. Leaders rent nice individuals however then go away them to work out what to do on their very own. “They find yourself siloing info in their very own minds; so, I make an effort to move info all the way down to my workforce simply as a lot as I do to rent the perfect individuals on the market. It’s labored for me.”
CISOs aren’t merely mentees on their journey – they’re mentors on their arrival. “I believe the one factor I might add to what we’ve already talked about,” he mentioned, “an anti-pattern I see in lots of safety practitioners is that they lack primary curiosity.” (An anti-pattern is a standard however regularly ineffective and doubtlessly counterproductive response to a typical drawback. A scarcity of curiosity is an anti-pattern to a profitable profession in cybersecurity.)
“If concerned with being on the high of your discipline in the long term,” he continued, “it’s best to spend your nights and weekends studying and enjoying with this know-how – you shouldn’t await someone to show you.”
He thinks safety has one way or the other misplaced a few of this pushed curiosity. “To start with, once I began, the one folks that have been loopy sufficient to do that job have been individuals who have been obsessed and would simply spend nights and weekends making an attempt to hack issues or learn to break issues or find out how protocols labored. And I suppose I typically really feel we’ve misplaced a few of that over time, that base degree of simply ardour and curiosity.”
Passionate curiosity, he suggests, is a path to success. “If individuals are not passionate and making an attempt to know all the small print, they often aren’t as profitable as different individuals who obsess over the small print to know every little thing from high to backside. The perfect individuals in any discipline are those with insatiable curiosity over something new – and this rising AI period lends itself to that driving curiosity about computing that existed 25 years in the past.”
An vital perception we are able to all achieve from high CISOs, given their wide-angle view of what exists and what’s coming, is an knowledgeable view of present and imminent threats. Flynn believes it’s much less the threats however their supply that’s altering. “Yesterday’s threats are nonetheless current in the present day – elite nation state assaults, extortion, IP theft and so forth,” he mentioned. “And so they’ll proceed tomorrow. However my focus is keeping track of how AI enhances attackers’ capability to conduct their assaults.”
The chances are cybersecurity will grow to be a battlefield the place defensive use of AI will search to mitigate the malicious use of AI. So, is AI a menace or a profit to cybersecurity? “Each,” mentioned Flynn. “On the menace aspect, it is going to improve individuals’s capability to conduct cyberattacks.” There will likely be extra, and extra subtle assaults as a matter after all.
“On the flip aspect,” he continued, “you will need to word that AI is an enormous a part of the answer to each the issues that it introduces, and the legacy issues which have been traditionally troublesome to counter with conventional safety. For instance, among the merchandise we’re engaged on embody the detection of vulnerabilities in code, getting these vulnerabilities fastened routinely, and creating safer code out of the field. The intention is that when individuals have code generated by an AI system, it’s intrinsically safer than conventional human coding.”
In brief, AI not solely introduces new dangers, however can be a significant element of the answer to each these dangers and the historic dangers we’ve been engaged on for a few years.
