Pretty much anything hardware based is like this. Everything is 100% closed source and bolted down such that inspecting it is outright impossible without extensive reverse engineering.
I definitely think AI is going to change this. Astra is shockingly good at reverse engineering. I was working with a proprietary software library and I just asked it how some (poorly documented) function worked and it just went off and disassembled it without me even prompting. I asked it if there was a way of disabling some error checks and it went and found some undocumented functions (not in the header), disassembled them and figured out how to use them for me.
I didn't actually even give it the ability to run this code and it could still reverse engineer everything.
I believe one of the feasibilities we have with electric locomotion is the standardization of components: electric motors, motor controllers, batteries and battery chargers. These being interchangeable will lead to lower costs through competition and more innovation.
It's disappointing that manufacturers are moving the other way to enable vendor lock-in. But only one manufacturer has to jump the fence and the others will be left behind.
