correct.

Commercial airlines are of great value to our lives. Who's questioning or denying that?

Horrible business to be in though.

they are not horrible business, some of them literally get invested by governments and get extra debt from them too so they can never go bankrupt? if they are at national level airlines, they survive no matter what.

that is not bad business? that is just private profits, socialize loses perfect business?

A good business is measured by the returns it generates.

They do not generate economic profits.

Yeah, I think AI model provider would goes the same way commercial airlines does

the money is infrastructure (hardwares, electrics, data etc)
