What has completely changed the field is LLMs. We now have employees of every sort building small Python scripts which actually work. Even installing Python and getting it up and running is something the LLMs help with. Obviously almost all of it is terrible, and none of scale, but for 90% it, it never has to run outside the personal computers of the employees who write it. Now the challenge becomes keeping the knowledge (and scripts) when employees change jobs. Though to be fair, the knowledge bit was always a challenge.
