It might be odd but I find Python so disrespectful to embedded devices. It pains me to think of all of the excess work those tiny things will do forever because of a very poor language choice.

More seriously, I think the long term effect of this will be truly catastrophic. There is an unfortunate effect whereby a tool's simplicity is able to attract newcomers to the space - which is great - but then severely limits progress by boxing them into this very small, simple, framework. It's very awkward when smart people and even professionals spend a lot of time fighting against the simplicity of Arduino or using weird, esoteric hacks as if it makes them a guru, just because it's all they know.

There needs to be an offramp. Micropython is the opposite - it's a one-way freeway to the middle of nowhere. It should be banished. So much human potential will be capped and wasted by this move.
