Personally I think the ones who will be remembered will be the ones who publish useful methods first, not the ones who succeed commercially.

It'll be Vaswani and the others for the transformer, then maybe Zelikman and those on that paper for thought tokens, then maybe some of the RNN people and word embedding people will be cited as pioneers. Sutskever will definitely be remembered for GPT-1 though, being first to really scale up transformers. But it'll actually be like with flight and a whole mass of people will be remembered, just as we now remember everyone from the Wrights to Bleriot and to Busemann, Prandtl, even Whitcomb.
