#3I wish we could just get away from x86 "standard" and move on. If there is something that still needs it, x86 emulation is very efficient nowadays. Just look what Apple has done with this ARM architecture. Even now, Qualcom's ARM processors running Windows are doing a fantastic job emulating x86 as needed.

They want to keep x86 going because they have cross-licensed patents which keep their market share a walled-garden. Anything else would invite competition.
Mind you, it's not just them. MIPS was pretty shady with their patent that even if trapped and implemented in software they sued so you could not compete without licensing and losing your margen. SPARC was open... until UltraSPARC IIRC and then they tried something similar.

> MIPS said the court’s ruling Friday rejected Lexra’s attempt to limit the claims of U.S. Patent No. 4,814,976 to hardware implementations of the unaligned load and store instructions (LWL, LWR, SWL, SWR) of the MIPS instruction set architecture. MIPS argues the claims should also cover software implementations like Lexra’s
That is what is so important about it RISC-V is that it being an open ISA creates a commodity with true competition instead of competing oligopolies.

Qualcom's chips do a very good job, but it's not perfect. Not sure if it's the chip or software, but if you need things to work (on either Apple or Windows ARM), emulation isn't suitable still. Apple gets away with it because they just wrote off the gaming market and everything else was forced to quickly migrate to the new platform.

IIRC Apple chips are particularly good at x86 emulation because they have a special option to run with an x86-compatible memory model which is stronger than the standard arm one. A generic arm chip is not necessarily good at x86 emulation.

Multi arch support has never been better and yet x86 is still competitive. Maybe in 10 years everything will be risc V but it doesn't seem to be happening very fast.

Move on to what? ARM? Is ARM better in every way than x86?
(genuine question)

Apple is the only one making ARM chips fast enough to be competitive even with emulation.
Qualcomm isn't on that level - they're only on par with AMD and Intel without emulation.
The market won't move from the x86 duopoly to Apple's walled garden because they have a fast chip. It's on ARM to make a licensable core that's so much faster than the x86 options that people actually move to it.
