Not gonna happen any time soon. The barrier of entry is massive.

Making decent drivers alone is a humongous undertaking: You have to catch up to the work of several decades - and it's a moving target. That's on top of just how difficult it is to design good silicon. Just look at how Chinese GPU manufacturers are struggling to match low-end cards from 10 years ago (even though they are lying and claiming they are matching high-end cards from one generation ago) with cards that have many times the power draw and cost - and all of that with far worse games compatibility.

Hell, even the giant that is (soon to be probably: was) Intel failed to leave a mark in the dedicated GPU business and they actually have decades of experience making (pretty shitty) integrated GPUs and (even shittier) drivers for them.
