- now imagine building entire systems tailored to each OS in just assembly
- imagine the next gen browser built in only assembly with a browser engine made in assembly
- imagine photoshop, illustrator, movie maker built ground up in assembly
- imagine an entire windows 12 operating system made in pure assembly
- the performance profile of each of the above must be absolutely wild
- since i am an an absolute newbie at assembly at this point, a sincere question to the some of the more englightened ones reading this, how and where do you recommend I learn assembly? I understand its different for x86 x64 and ARM? where should I start?

  I would recommend RV32I. I started with Z80's, but that's something too esoteric for 2026. Thanks for giving rhun a try!

  Btw if you're interested, you can browse <a href="https://kolibrios.org/en" rel="nofollow">https://kolibrios.org/en code (<a href="https://github.com/KolibriOS" rel="nofollow">https://github.com/KolibriOS) for a more complex codebase. Not my project, but it's a quite mature assembly repo.
