If a highly consumer tech literate person with a near unlimited budget (either from freebies or business expenses or just because he's a multi millionaire) struggles with this stuff, you can be sure it's not ready for even enthusiast adoption.

> highly consumer tech literate person

Watching his videos on this subject I do not get the impression that he falls into this category.

If he's not then pretty no one is; and the solutions are overcomplicated.

My grandmother, at the grand age of 95, shows better understanding of tech than is demonstrated in those videos.

Care to highlight any specific example?

Just looking quickly at one video where he had trouble with heating, they seem to use, lets say, not exactly finished products. Instead controlling things via Home Assistant. Which does not to me scream having lots of money, even is he has that. I believe there are much more expensive and more ready-made systems than what was used there.

I think you're talking about the latest one where he's mining bitcoin for heating. I haven't seen that video, but there is a playlist of 30 videos about his new house, and a lot talk about different smart-home aspects which are top of the line and yet just don't work.

I think the one that shows the most glaring issues is https://www.youtube.com/watch?v=KkAiXzKOTNY about his smart lights.
