They would look the same really. The word size being 128 instead of 64 doesn’t really change anything about the architecture. It just means the proc’s registers are 128 bits in size, the system bus is 128, each RAM address and data is 128, etc. The only difference would be significantly more expensive to crunch ridiculously large numbers. So really not much benefit. I expect 64 to be the standard for quite a long time, maybe forever, because we have much bigger bottlenecks to worry about.

Big money through a contracting company? They take a cut, I’m sure. Still worth it?

Gut ecology is complex and everyone’s is different and it changes over time and with age and when you have to take antibiotics, etc. There’s no one sure-fire way to just eliminate it.

Sounds like engine braking

Imagine getting a can of purple paint and trying to figure out exactly how much red and blue dye was used to make that exact purple. Now imagine doing that every few lines of code in a code base of say 10k lines. That’s basically how decompilation goes. It’s extremely hard and even if you’re able to figure it all out, it’s still impossible to ever know what was actually originally written.

What you’re describing though does have done truth to it. There was a time when you could get a program from a magazine, type it all in to your commodore 64, and then it would run a pacman clone. These, line python today, are not compiled. So to have the program means to have the code too.
