The reality is that by now we should already be at a level where common programming would be like Wolfram everywhere.
Maybe agents and LLM driven code generation is how we eventually get into the next abstraction level, sadly won't be without casualties with smaller team sizes, when so much can be automated away.
What aspects of the Wolfram language should be everywhere? The easy access to lots of datasets? The easy access to lots of mathematical functions? CAS in general?
