15 years ago I remember a lot more experimentation was encouraged and a lot less process. I could have an idea and get an enthusiastic "go for it". I could improve the way we deployed code. We had some semblance of "agile" but it was much more informal. I had passwords to everything.
Now everything is locked down. Everything is decided. The technologies are chosen, the process is complete and rigidly enforced. I pull tickets off the board at the start of a sprint. I finish the tickets. Day in and day out.
