How so? If I build a simple app that does its job and does it well, I don't need to work on it for 40 hours a week for the rest of my life. After the initial effort, you can put in almost no work, just periodic maintenance, and you can keep bringing in sales.

There are lots of opportunities like this. There is nothing morally or ethically questionable about this. It doesn't require you to over-inflate your prices. That is the power of software. The VC hyper-growth world is heavily focused on continuously changing your software, but that isn't a requirement (and in fact, is often not desirable to your customers).

What if someone works 30 hours a week performing a service which is not yet automated, but uniquely theirs, like their own standup comedy.

Contrast that with the replicable software example.
