Imagine believing that your life is just spread out over some “temporal dimension.” Hahaha. The self at 12 pm never flows to 12:00:01 pm. So the conscious experience of that self at 12pm never begins and never ends. That particular self simply has that one particular experience, and there’s not much else to be said. According to these weirdos, the experience would be “timeless.” Saying that the experience never ends could be misleading because it’s supposed to be “timeless.”
The B theory really isn’t conceivable, because it’s incompatible with conscious experience, but if you do try to imagine these zombies’ fake conscious experience, you get some kind of timeless thing that is obviously not what real experience is. The fact that they can’t understand this just proves their zombiehood.
There's already evidence that some people don't experience time. The only thing to do now is determine who.
For example Bernardo Kastrup keeps saying he's not conscious of anything existing or anything happening, only conscious of the NOTHING . He even wrote an article for Scientific American saying he doesn't experience a flow of time.
Bernardo Kastrup: "There is no difference between everything and nothing. NONE WHATSOEVER. IT'S A COMPLETE DELUSION. NOTHING'S GOING ON." https://youtu.be/kkHC7t6QVhc?t=6071
Bernardo Kastrup part 2: "And I think it's true. That's the magic of existence. Nothing ever happens. Nothing ever happened. Nothing will ever happen." https://youtu.be/BG31Oz0VWmI?t=2893
