That's a great question. To the extent that increasing the budget caused more smart people to get PhDs and more of them were able to contribute to the scientific effort (as well as help bigtech develop ML and contribute back to science), I think it was a good idea.

It might have been better executed- somehow matching the increased supply of grad students with increase supply of faculty positions, or perhaps just growing it more slowly to let the inequalities equilibrate a bit more. But ultimately, I think it was a good thing, in that it increased the total science being done.
