I don't know. Would we have called prior software "internet wrappers" or "rest api wrappers"?

Someone else above/below commented "Marketing --> Product".

I see it that I have a problem, someone solves that problem. I pay $$ per month. Everyone is happy.

I'd say "solution" or "product" and not get stuck on the technical details (for/to which I agree with you but 90% of the people don't care).

When you buy milk you don't buy liquid+container+shipping, you buy food. You consume the food. Belly feels nice. See you tomorrow for another bottle.

I don't agree with this word trickery of 'everything is just a wrapper'. The internet, browsers, and rest APIs are much more like scaffolding or 'infrastructure'.

Internet (and/or browser) :: website or webapp

is not the same as

OpenAI/Antropic/model company :: GPT wrapper

There is a substantial qualitative difference, at least at this point.
