As a justification of what he’s already doing this is relatively weak and the real answer is “we will see.” It’s possible his business plan works out and him having all the ram is the best allocation (as he and his backers have already decided).
But it’s also possible this just makes his main “killer app” evaporate. Who is going to make use of these LLMs if common people can’t afford a decent laptop to use for such applications? Cloud isn’t the answer as it competes for the same compute resources that we’ve already declared too precious for common people. It’s essentially a tautological claim, vacuously justifying something that’s already been done with the ends of having done that thing.
This is a far cry from intelligent thought being a universal utility that you can pipe into your house like water or electricity, as I believe was initially claimed.
