This all sounds like useful stuff I'd potentially use but I don't see it solving the core problem that programming is difficult. I've long worked in environments where "basic code intelligence" works and it is certainly useful but the problems it solves are not what makes programming hard.

Programming is hard because it's hard to define the problems that need to be solved, hard to design good solutions and often hard to implement them efficiently. A smart IDE is a useful tool but it does little to nothing to address the fundamental difficulty of programming. The real challenge to making programming more accessible is how to teach/train people to be better thinkers and problem solvers (and I include myself in needing that).
