Collision exclusive: The economic impact of generative AI

For the past 60 years, despite all the setbacks, neural networks have steadily improved. This talk explored the forgotten history of the field, and why we must must dare to dream.

Can we rule out near-term AGI?

Meredith Whittaker used to work with Google, where she famously led the walkouts in 2018. She also worked for the US Federal Trade Commission as a senior AI advisor. Meredith is now the president of encrypted messaging app Signal, and a fierce critic of big tech.

DevOps today means shipping faster – but also defending harder. With AI-generated code, shifting stacks, and quantum disruption on the horizon, what does it take to build secure, scalable systems in an environment that’s always under attack?

As AI’s capabilities continue to expand, what does this mean for the developers of the future? What can be done to create synergy between engineers and the tools they use? Is software development still a viable career in the wake of vibe coding and the assistants that enable it?

Everyone’s a dev now

Blockchain and open-source tools are resurging as AI unlocks new use cases and AR/VR reshapes how we experience the internet. Will these novel technologies help us escape from centralised, closed systems – or are we just rebuilding them under new rules?

The web’s future

Online safety is an arms race, and AI has accelerated it. As cyberattacks become more sophisticated and AI-generated code going unvetted for compliance, applications, devices, and systems have never been more vulnerable. In a world that’s increasingly lacking shutdown protocols, how can we safeguard our security?

How secure are you?

As quantum transitions from experimental to practical applications, the technology is slowly becoming embedded in industry. What developments will quantum empower in healthcare, finance, and AI? And what do the builders creating quantum infrastructure believe will come next?
