reality most of the real world successful projects are mostly untested because that's not actually a high ROI endeavor. it kills me to realize that mediocre code you can hack all over to do unnatural things is generally higher value in phase I than the same code done well in twice the time.
I think the pendulum swing back is going to be designing code that is harder to make bad.
Typescript is a good example of trying to fix this. Rust is even better.
Deno, I think, takes things in a better direction as well.
Ultimately we're going to need systems that just don't let you do "unnatural" things but still maintain a great deal of forward mobility. I don't think that's an unreasonable ask of the future.
