I've noticed that too, LAMP stack vs MEAN stack etc. Part of it seems to be that software languages have "flavors" like natural spoken language does, so that one seems natural to one person and foreign to another, much like how DHH took TypeScript out of Rails, and I can't read Rails code or live without static types. Also college kids are always learning what the last generation already knew (like Lisp) and reinvent everything in it with the vigor of their youth and it gets popular, which I imagine is how Rails and Redis both started and caught on. But sometimes there are genuine innovations, and we can't build on them until someone comes up with them, much like how we couldn't invent machines until someone figured out that we could just use the lever to make gears to transport energy, which Archimedes didn't think of. And the more we learn collectively, the more these things spread. I wonder if this means it'll all stabilize into a JavaScript-like toolchain one day. Maybe Gary Bernhardt was right all along.
