I don't agree. Important code will need to be audited. I think the language of the future will be easy to read by human reviewers but deterministic. It won't be a human language. Instead it will be computer language with horrible ergonomics. I think Python or straight up Java would be a good start. Things like templates wouldn't be necessary since you could express that deterministically in a higher level syntax (e.g. A list of elements that can accept any type). It would be an interesting exercise.
If AI is going to write all the code going forward, we can probably dispense with the user friendly part and just make everything efficient as possible for machines.
