It doesn't matter how fast I get at regex, I still won't be able to type any but the shortest (<5 characters) patterns out quicker than an LLM can. They are typing assistants that can make really good guesses about my vaguely worded intent.
As for learning deficit: I am learning so much more thanks to heavy use of LLMs!
Prior to LLMs the idea of using a 100 line PostgreSQL query with embedded regex to answer a mild curiosity about my use of alt text would have finished at the idea stage: that's not a high value enough problem for me to invest more than a couple of minutes, so I would not have done it at all.
