A bit about me.
I'm Aryan Yadav, co-founder and CTO of NeoSapien. I build AI systems and keep coming back to questions about consciousness: where thoughts come from, what it means to be a self, and what happens when we sit still and pay attention.
I read Vedanta and Buddhist philosophy alongside maths, science and science fiction. Some of that reading ends up here. So do the questions I haven't found a good answer to, and the experience of trying to build things while figuring them out.
I also love martial arts. I'm a karate black belt and have competed at the national level.
