scaling these solutions will prove to be counter productive. If you are thinking of scaling you are still trapped in the current paradigm. This plumber guy is only unique in that he read the news and pushed a little harder to see what the actual f is going on. In the days that come, every single person who is serious about their job will do and experience the same thing.

I'm not saying this particular individual is wrong in trying to build his solution to the market. Maybe there is some VC money to be made in this moment. But as AI in the workplace gets normalised, most people will either come up with solutions for their problems, or they will ask someone they know to help them with this.

scale will only matter if you are explicitly building a platform. That will still require real software engineering skills.

As for hardware interfacing, if I am not mistaken, almost all companies selling hardware right now still behave like babies when it comes to users getting access to the software inside it. They void warrantees, sue them, so on etc. For ambitious user driven software innovations in the hardware space the companies should open up their interfaces. I don't see this happening at all not only because of the companies' greed but also for regulatory and safety reasons.
