Not really because the desktop varities have that much RAM. If they cant put the same size GPU due to power limitation they should atleast put that much RAM(I understand RAM consumes power too), espcially with Apple with unified memory is gonna handle larger stuff.Get true pro card if you want to do real work with AI or productivity. It was already kind of generous lol for them to even allow those pro app to work on non pro cards. As for gaming nvidia need them to keep buying future cards. Just look at AMD. one of the reason why gpu sales end up tanking was because there is already tons of 12GB/16GB gpu flooding the market after the mining craze.
