My career was using C# and JS, and LLMs have caused me to lose interest in learning more. I was always a hobbyist Python and Ruby user. I prefer to put my efforts towards skills that are still useful. Software as a craft is dying, no different than being an expert at riding a horse.
The important part now for a developer is a very strong command of the English language, for both the LLM as well as the rising importance of client interactions. As the space is very competitive, so you need to offer value or form a union so you can regain back some of your lost negotiating power.
Most of the developers I worked with were very poor in that area. I worked hard and was deemed a "top performer" in my last job, but it was equal parts perception management. This is what you should be thinking about and focusing on going forward. Improving your linguistic skills, and polishing your social skills.
Otherwise, for someone like me who grew up in a machine shop and mechanic's environment, anything new I learn is more brawn and brain going forward so I stay relevant as a human being. And no longer just brain like software was.
