the "value" of nvidia to the "AI" companies is their tsmc fab contract
they don't need CUDA, they don't need the 10 years of weird game support, even the networking tech
they need none of nvidia's technology moats
exactly same as the crypto, where they just needed to make an ASIC to pump out sha1 as quickly as possible
which is really, really easy if you have a fab contract
at which point their use of nvidia dropped to zero
