You say that based on 30-40 years of companies not really knowing what they were doing, but we live in a world where hardware manufacturers ABSOLUTELY know how to make nearly unhackable, locked down hardware. Smartphones are already like this - if the manufacturer decides you don’t get to install a custom OS, unless you’re lucky enough for there to be an exploit, you don’t get to. Same goes for game consoles. That knowledge can easily be applied to these to make these, if not completely unhackable, so unstable and inconvenient as to be almost the same. We are absolutely entering this nightmare phase.
