For what purpose exactly?

I have Arduino and raspberry Pi boards. I am perfectly capable of hand writing code that runs on these machines. But they are sitting in the drawer gathering dust, because I don't have a use case -- everything I could possibly do with them is either not actually useful on a daily basis, or there are much better & reliable solutions for the actual issue. I literally spent hours going through other people's projects (most of which are very trivial), and decided that I have better things to do with my time. Lots and lots of people have the same issue.

And Claude Code is not going to change a single bit of that.

I think the reality is that the maker movement slowed down not because it’s hard to learn c++ but because people don’t care enough. Will maybe twice as many people participate now? Sure. But that’ll still be a small fraction of people.

IoT security was already enough of a shitshow before vibe coding, now we can reach levels of botnet never thought possible.

Not sure I see it like that. Micropython removes most of the rough edges of doing embedded C. If you prefer no code then I suggest ESPHome for your ESP IoT projects.
