If Commodore had have survived, any modern "Amiga" would similarly likely have been a very different platform, only sharing the name (e.g., consider that Commodore's plans were at one point to move to RISC machines running Windows NT).
Yes. And it's a good thing... Much like cars done today have nothing to do with cars made 24 years ago, fortunately!
Fortunately, today's "amigas" have nothing to do with original "amigas", but unfortunately, todays "AmigaOS" is the same as the one we had in 1985. Same limitations.
