My big problem is that nobody is working on truly innovative programming languages anymore.

Everyone wants to build another iteration of a C style language with incremental improvement for little benefit.

The problem is that we probably reached the general purpose frontier a long time ago and there are just a few surface level things that need to be changed here and there, which is not worth a whole new language.

It goes against the programmer's ego, but the way forward is by adding more restrictions. The people complaining about the borrow checker in Rust just don't get it. If you want programming to improve, you will have to give up the ability to write every conceivable program.
