Yep. And money is just another kind of chip. What's so great about money?
It gets exchanged for hamburgers

And, yet, somehow, functional languages have been doing this since forever? I jest, I jest! There's an entire field of study focused on this! I'm no expert, but imagine you've got a singly-linked list, and we're going to allow only push_back() and pull_back() (no insert()). Let's go ahead and let multiple owners have at this list. If A does "pull_back()" what really happens is A has a local "tail" pointer that moves back along the end of the list and has a new belief about the end of the list. When A does "push_back()" it begins attaching links at its new tail. Since the links just "point backwards" without modifying the old links, this doesn't mutate the list "as is", it only mutates A's version of the list. So, if B is also looking at the list, it could just start doing "push_back()" and add its own "tail". The result is a data-structure that's a "bunch of shared singly linked lists" in a bush structure that's more akin to a tree than a singly linked list.
You can do the same thing with binary trees and other structures. It's more fiddly, and there's definitely places where single-ownership allows mutability "under the hood" for real performance gains, but that's the basic idea.
Interesting, I didn't think about that, so it is copying on write but on a more granular level
Which assembly? Assembly with macros? Assembly with synthetic instructions?
If you use
mov %i0, %l0
or %g0, %i0, %l0
I was thinking of x86 when I wrote that, also I am not sure macros count as an abstraction level since they are just preprocessors?
What I meant to say is that since there is no way to directly write microcode, assembly is the lowest level software can target.

Python discovers immutable data, and gets it wrong. Frozendict is a blunt instrument - instead of a mutable free-for-all, it just locks the data for the entire lifecycle. Brace for the wave of code littered with deep copies, proudly proclaiming how functional it all is.
If you want real immutable data structures, not a cheap imitation, check out pyrsistent.
How else would you "modify" immutable data other than by copying it?
And yet modern assembly does not correspond 1:1 to the micro-ops the CPU runs or even necessarily the order in which they run.
Both ISA-level assembly and C are targeting an abstract machine model, even if the former is somewhat further removed from hardware reality.
Sure but from software POV assembly is the lowest level you can target
DEC went down the drain, Xerox is 1/1000 of IBM's market cap. IBM made its own, superior by its relative openness, personal computer that ended up running the world, mostly maintaining direct binary compatibility for 40+ years, even without IBM really paying attention.
How much did IBM itself benefit from the PC? I thought the clones ate their lunch there

Every time I see this in the comments it's funny that they don't block me while connecting from country whose digital privacy laws are basically an even stronger version of the GDPR. Tells you about their true reasoning.
seriously, what would their true reasoning be
What you describe I think is what most other people hate the most about python. The fact that everything pollutes the global environment, which then becomes a mess of things depending on various versions, which also ends up breaking tools included in the OS and suddenly your whole system is effed.
System package management is a mess in the first place, if you have a program that uses python then all the packages that it uses need to be installed globally, so you have python packages bundled as system packages which can conflict with that same package installed with pip.
If you used the server to mine Bitcoin, you would make approximately zero (0) profit, even if somebody else pays for the server.
But also yes, Monero has technically held up very well.
