I don't fully agree with the quote. You can't really outsource thinking nor understanding. You can outsource the generation of streams of tokens that may or may not be appropriate for what you're looking for. But you absolutely have to know what you're looking for, or have a very solid intuition of what it should look like and behave, otherwise you're just digging your own grave.

The skill is in making the LLMs reliably generate useful and pertinent streams of tokens. That takes work, reading the output, intuition, experience, rigor, real commitment to doing good work, not fall prey to being lazy, etc.
