Andreessen says AI coding can make engineers 20x faster — and could still trigger layoffs

Marc Andreessen argues that AI coding is creating a new kind of overdrive: some engineers stay up all night because the opportunity cost of sleep feels too high, while others say they are getting roughly 20x more productive with AI.
He frames the pessimistic case as one of demand limits: if the world only wants a finite amount of software, then extreme productivity gains could translate into mass unemployment. The post also highlights a broader thesis that scarcity has shaped what people think they want, and that AI may expose more latent demand than traditional markets ever measured.
