Really? At some point syntax became kind of a vague sense of color on top of the data flow, which is ultimately the same in any language. I don't even recall what it means to be proficient in one language versus another—surely most career programmers can ramp up on any given syntax or runtime in a relatively short period of time. The hard part is laying out the data flow.
Granted, AI can definitely ease that ramp-up time at the cost of lengthening it.
You still get to be proficient in an environment. I've got around 10 projects open in different Cursor windows. Logging in each of them is one or more of: logger.info, log.info, echo, eventLog.WriteEntry, console.log, syslog, printf, active_span&.set_tag, puts, rollbar.info, ... (and more)
It's not the ramp up time. There's no problem with learning yet another one. There's a problem with remembering them all as you switch between the projects. Most of the time LLM will know exactly what to use, how, and what data I want to log. Which will take way less time than me rediscovering how a specific project I haven't seen in weeks does things.
