Today he's a Board Partner at Andreessen Horowitz (a16z) and writes Hardcore Software, a serialized Substack memoir chronicling the rise and fall of the PC revolution from the inside.

In 2023 he published the Techno-Optimist Manifesto and in 2024 pivoted to advising the Trump administration's DOGE initiative - cementing his status as Silicon Valley's most opinionated, polarizing, and consequential voice.
