Where are the open source planes, trains, and automobiles? Medical equipment? Nuclear reactors? Open source cannot afford the quantity control/verification need for these domains. It’s the same for phones. At best you’re going to get an insecure mess.


People can and do build their own automobiles all of the time. See: https://www.youtube.com/@GrindHardPlumbingCo


Open source literally drivers ADA compilers, toolkits, DICAM readers and whatnot.

On security, your lovely propietary NT based kernels had so many CVE's and attacks that you could fill gigabytes of text with these.

Trains - not so hard, it's getting legit real track time that's the issue - and you can always 'cheat' with a Hi Rail Pickup Truck modification.

Automobiles - .. you are kidding, right? You've never built (or met a builder of) a road certified car, truck, or other vehicle?
