Ok, so what has happened historically when we hold a tech stack constant for 10 years? Versioning proceeds, but everyone consolidates on a thing?

Python? => Data science. Sure, python is just importing the C tools that do the heavy lifting, but look me in the eye and tell me R, S, SAS, or SPSS won.

C? => I mean, everything? But what happened in the first 10 years? Proliferation of operating systems and linear algebra libraries?

So, generally, the grey beard talent consolidates their intellectual contributions and uplift everyone else. Is that true? -ish? Missing the mark?

Guys, I'm a knuckle-dragger, I genuinely don't know what I'm asking. What are the tech stacks that were held constant (by whatever factors) for a decade, and what came out of it?

Is this the decade where art directors takes over gaming?
