The Open Source Substrate for Quantum with Ben Castanon

What does it take to build durable open-source infrastructure for a field that hasn't yet delivered on its biggest promises? Ben Castanon, the first-ever CEO of Unitary Foundation, joins Sebastian to talk about the structural funding gap facing quantum open-source software, why nearly 40% of full-time contributors go uncompensated, and what a "Linux for quantum" would actually require. It's a candid conversation about community, memberships from companies like NVIDIA and IBM, and the case for treating open tooling as public infrastructure rather than a nice-to-have.
