Sociologist and comedian Harald Eia argues in a TEDxOslo talk that Nordic social democracies produce more rich people per capita than the US or UK. He credits high taxes, welfare and strong unions for creating a safety net that enables risk taking.

A 2007 Google Tech Talk in which Cliff Click of Azul Systems presents a lock-free concurrent hash table that scales to 768 CPUs. He explains why it is correct by reasoning in a different way than usual happens-before and memory-order arguments.

Leslie Lamport argues that programmers, like architects, should write rigorous specifications before coding, especially for concurrent and distributed systems. The talk introduces the case for writing specs (the TLA+ mindset) as a way of thinking above the code.

Greg Young's Code on the Beach 2014 talk on CQRS and event sourcing. He argues mature domains are built on facts that occurred rather than current state, and covers the business and technical benefits.

Tristan Harris and Aza Raskin of the Center for Humane Technology present why current AI capabilities pose catastrophic societal risks. They argue companies are racing to deploy without adequate safety, and that institutions must adapt. It was given before GPT-4's launch.

Kevlin Henney's GOTO 2018 talk argues that much of what looks new in software is a recycling of concepts with long histories. It draws on history to show the slow, steady current beneath constant churn in frameworks and trends.
