One is that we live in a universe in which the past, present, future are equally real.
Time travel is absolutely one hundred percent impossible because you can't travel to places, to times, to moments that don't exist.
Dean Buonomano is a neuroscientist at UCLA who has spent thirty years on a question most people assume was settled.
This brings a new angle to the argument about machine consciousness.
If time is something a brain has to build and these systems have none at all, the question stops being when they'll get there and becomes whether they can.
He's also a committed presentist.
The past is gone, and only the present actually exists, which means there's no coming back to fix not subscribing, so you may as well do it now.
What would happen to consciousness when they paused the computer running that program? Would consciousness be paused in the state that they were in or would conscious disappear?
They're-- feel as human as they do, but they absolutely lack something as fundamental as time.
This has, uh, very, very profound implications for whether they can achieve cognition in any way that we can.
Dean, for the listener at home who might not be familiar with you or your scientific work, what's the most important context for them to understand? Where does that story begin?
Well, I think it's always up to other scientists to sort of determine our contributions and, and what we have or have not done.
But, but what I like to think, Evan, [chuckles] one of the things I like to think is that, um, one of our major contributions to our understanding of how the brain works is how it tells time.
