In this episode of ‘This Week in Consumer’, a16z General Partners Anish Acharya and Erik Torenberg are joined by Steven Sinofsky - Board Partner at a16z and former President of Microsoft’s Windows division - for a deep dive on how today’s AI moment mirrors (and diverges from) past computing transitions.

They explore whether we’re at the “Windows 3.1” stage of AI or still in the earliest innings, why consumer adoption is outpacing developer readiness, and how frameworks like partial autonomy, jagged intelligence, and “vibe coding” are shaping what gets built next. They also dig into where the real bottlenecks lie, not in the tech, but in how companies, products, and people work.
