For years, I've heard from my fellow computer scientists that "the brain is a computer" or "we can simulate brains in a computer." I think both are wrong, and, now that we're hearing them from corporate tech leaders too, it's no longer just an academic topic. 🧵 aaronhertzmann.com/2026/07/13/b...

The Brain Is Not Just A Computer, and Cannot Be Simulated by One

Digital computers perform fixed logical operations on clock cycles; brains are biological systems of staggering complexity.

Today was my last day at the Samsung AI Centre Toronto. It’s been an AWESOME 8-year run. I’ve learned a tremendous amount, worked with incredible people, and built lasting friendships along the way. 1/2

Back to the lecture prep grind. VERY early version of my lecture on Policy Gradients. With #computervision and #robotics research appearing to converge, at least based on #CVPR2026 and my European tour conversations, it feels like good timing 😉
