Ultimately though in the long run.. They invented the tech, have a large cashflow generating business subsidizing R&D as well as sales, with network effect of existing B2B relationships.

Further they have their own TPUs, datacenters, etc on which to run their models.

Plus existing data they've squirreled away over the preceding 30 years from books, web, etc.

Just seems like a lot of efficiencies if its going to come down to cost.
