> Serverless won't be profitable because the people who need it don't make money.

You seem to implying only applications with huge numbers of users can be profitable. This statement ignores a tremendous amount of (typically B2B) applications that provide enormous value for their users but don't see a lot of traffic.

I have worked on applications that are at the core of profitable businesses yet they can go days, in some cases weeks without any usage. Serverless architecture will be a real benefit there once it matures.
