Physicist turned banker. Writing about technology, finance, and philosophy.
I have less than 100 years here. This is where I document what I think and learn — mostly for myself, but you're welcome to read along.
AI, software, the future of computing, and what it means for us.
Markets, money, crypto, and how capital shapes the world.
Consciousness, existence, meaning, and the hard questions.
Unfiltered thoughts on technology, markets, and existence.
