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.
If someone offered you 1BTC for $10k right now you would bite their hand off. At $14k it would be still some of the easiest money you've made in your life.
Even if you have the most cynical opinion of cryptocurrency, you must admit it's alive and well. It is as long as there are enough people who believe that it is - and your honest answer to the above would reveal that you know that to still be very true.
It doesn't feel different. The evangelists will hurt and the whole crypto industry is set back, the cynics gloat and revel in the schadenfreude and claim for the 748th time that crypto is dead... Until 12 months later when we do it all over again.
It's not the biggest, it's not the first, it won't be the last, it's nowhere near the most catastrophic. At least let the dust settle before making such bold declarations. Any such declaration at this point is more hope than expectation.
