Funny, I learned the exact opposite lesson. Almost all software suck, and a good way for it not to suck is to know where the developer is and go tell them their shit is broken, in person.

If you want a large scale example, one of the two main law enforcement agency in france spun off libreoffice into their own legal writing software. Developped by LEOs that can take up to two weeks a year to work on that. Awesome software. Would cost litterally millions if bought on the market.

I feel bad for whoever gets an oncall page that some executive's vibe coded app stopped working and needs to be fixed ASAP.

Your conflating the example with the opportunity:

"Cancel Service XXX" where the service is riddled with dark patterns. Giving every one an "assistant" that can do this is a game changer. This is why a lot of people who aren't that deep in tech think open claw is interesting.

Do they? Because I know a lot of people who have (as an example) terrible setups with sales force that they have to use.
