I want to push back on this part:

Only if Microsoft acquires a major CPU chipmaker.

In the USA, and other parts of the world, a small number of Billionaires are buying up everything. A small number of wealthy people could each own a part of the supply chain and for it on the vast majority.

For extra enforcement, add in a legal or cultural push for reporting or shunning violators through the media companies owned by that same group.

Just adding links for the lazy…

The computers in the store, yes. I expect all computers in the store to be phones and the cell company will verify.

Open Source computers will be more important. Might need to brush up on wire wrapping… (Implication being that chip supplies might become dedicated to only those manufacturers that lock the product down.)

Elsewhere in this thread. Anyway, here is what I had said:

There are “electric truck” conversion books from the 1970s. (Only trucks as they used lead acid batteries, which are still extremely heavy for useful amounts of stored energy.) This indicates it is not extremely complex, though possibly still very complex. (My reason for this assessment is from reading a few of them, but never implementing any of it.)

Anyway, here is a title to look for, from 2011, " The electric vehicle conversion handbook : how to convert cars, trucks, motorcycles, and bicycles : includes EV components, kits, and project vehicles" by Warner, Mark, ISBN: 9781557885685 1557885680.

2021’s “Convert It!: A simple step-by-step guide for converting any classic car into an electric vehicle.” by Ron Toms, ASIN B093CH8HR7.

Neither are from the 1970s, but both are likely more useful anyway. There are also likely others that I cannot immediately find. I have read neither, yet.

I also live in Florida and love to jet ski. It was great seeing you in person last Saturday. Wow, what a day.

Who else was there? Must have been many of us. Just jet skiing in Florida.

This is a good idea. And a good use for AI.

Likely a lot. I posted elsewhere, but there were books on this in the 1970’s.

As for a detailed answer on the rest: I have no idea.

Just a reminder that “kit cars” exist. Their existence makes the idea of “open source” cars seem more reasonable to me in that one does not need to make a large company, it is possible (though likely not profitable or cheap) to be a small car company.
