That's not the fundamental problem of all AI research. That's the fundamental problem of all software engineering! Especially integration complexity is todays' biggest complexity in any significantly complex product. And you can't cheat yourself around it. We managed to cheat ourselves around growing complexity in subsystems by isolating them more and more, which allowed us to tackle the complexity with more people working in parallel. But that just further increases the integration complexity, where we don't know a way to effectively scale our approaches to deal with it. The only way we know is "cutting corners": creating a system that's just working well in 99% of cases - leave the small problems of the remaining 1% unsolved, hence there's nothing to integrate for those. Works well enough for production use in a lot of situations. Doesn't work at all when it comes to Level 5 autonomous driving. And that's what Elon either doesn't understand or actively ignores.
