We aren't in the 1980's any longer, most of these systems are way more powerful than a typical 16 bit home computer, and incrediblly as it sounds, those 16 bit home computers still had better tooling than most MCUs have nowadays.

Anything that brings MCU tooling into the 21st century is very much welcomed.

I haven't yet shook the feeling I got when I first realised my thermostat has more processing power than the computer I had as a child.

But also the devices this OS is aimed at will often be doing more than those computers were ever capable of, such as driving a full-colour display with touch interface while running a web server and wireless networking stack.

Agreed. It is really nice to have an OS like this. It will get a lot more people involved in the development. I would even think of scaling this up to more powerful processors and perhaps have it even on smartphones.
