I built my career on Solaris and it got rugpulled by Linux.
That wasn’t because of software, it was because of hardware. Linux’s cost advantage existed because Sun hardware had huge margins, because their software was basically free.
AI will probably be a repeat of this. Whoever can come up with the hardware solution that minimizes the cost per token will win.
I believe the 5090 still holds this crown, but someone certainly knows better than I do.
