The idea is an ai that sends 2 emails instead of 4 or reduces the emails u get?

It shouldnt really bother you unless u believe them. If anything it should motivate u even more. Entrepenuers are literally part of the economy. Its not real work its actually realer and harder, higher risk and higher possible rewards.

What are their arguments against it? It shouldnt be difficult nowadays to dismantle those arguments.

Just pay someone on fiverr to get it all done for u, if ur making money its a no brainer investment…
