I mean those are fair points, though respectfully I think there are cases for SPAs where SSR won't do. But that's not what we're talking about.

Referring to SPAs as a "zero-interest-rate phenomenon" implies that SSG/SSR models are more efficient in terms of financial cost of deployment. I don't agree this is necessarily the case, and I think SPAs can be developed and deployed sanely and cheaply also.

Vercel is doing some amazing things, but it's also innovating in ways that occasionally lead to "lock-in", in the sense that moving away from Vercel would involve a lot of friction. So I think it's fair to point out that you have a financial interest in convincing people to adopt delivery models that your business streamlines.
