Who will pay for the ongoing development of (near-)SoTA local models? The good open-weight models are all developed by for-profit companies - you know how that story will end.

Apple via customers paying for the whole solution ( eg a laptop that can run decent local models )?

I think Apple had something in the region of 143 billion in revenue in the last quarter.

Not saying it will happen - just that there are a variety of business models out there and in the end it all depends on where consumers put their money.
