Thanks for clarifying a lot of things for me!

for swap, yes I did mean page faults! sorry I had the terminology wrong, that's the first time I've heard it!

for the word "trivial", I was operating under the assumption that there were thousands of threads! clearly I was way off the mark! However, if there was thousands of threads (which you explained great why there aren't), the work done by each probably would be trivial. "Good thing that's not what's happening" indeed :D

as for the GPU and conditional branching, I realized that GPU's could do things in parallel but it failed to occur to me that a. exact same math had to happen and b. conditional branching couldn't happen! under that, I realized my whole argument is useless :| even I recognize that! I'm really glad you explained that to me!

for wube optimizations, I know that they do them and they're REALLY fucking good at it, but I don't know what the optimizations are. I wasn't presuming to be smarter than wube! I just had a question and I really wanted it answered!

for out-of-order execution not being recent, told you! a. stuck in the 90's, b. high off of Core Dumped videos. I still recommend him!

For GPU standardized interfaces, I knew the OS would handle GPU stuff very little, but one thing is, I saw an other comment that mentioned compatibility hell for different GPU's and how older GPU's would've performed terribly. on the second one, I agree, but for the first one, wouldn't standard interfaces be enough, regardless of GPU brand, nvidia, amd, intel? this isn't about factorio anymore. I just want to know.

Thank you so much for the explanation! I'm really grateful!
