These exist. Just now I triedfinding such a video for a medium-sized contemporary AI devtools product (Mastra) and it took me only a few seconds to arrive at https://www.youtube.com/watch?v=fWmSWSg848Q

There could be a million of these videos and it wouldn't matter, the problem is incuriosity/resistance/change-aversion. It's why so many people write comments complaining about these videos not existing without spending even a single minute looking for them: they wouldn't watch these videos even if they existed. In fact, they assume/assert they don't exist without even looking for them because they don't want them to exist: it's their excuse for not doing something they don't want to do.

That video was completely useless for me. I didn't see a single thing I would consider programming. I don't want to waste time building workflows or agentic agents, I want to see them being used to solve real world difficult problems from start to finish.
