Hey, I'm Dario.

I’m a security engineer. I protect data for a living and chase my curiosity the rest of the time. That usually means AI, cybersecurity, philosophy and geopolitics.

This site is where I write, keep my bookshelf, and track what I’m building.

Thoughts on Free Will

I’ve been thinking about free will for a while now. It’s one of those topics that sounds simple on the surface but the deeper you go, the more it messes with you. Do we actually make choices, or are we just incredibly sophisticated dominoes falling in a sequence set in motion long before we were born?
