Most programmers don't need to develop that skill unless they need more performance or are modifying other people's binaries[0]. You can still do plenty of search-and-learning using higher-level languages, and what you learn at one particular level can generalize to the other.

Even if LLMs make "plain English" programming viable, programmers still need to write, test, and debug lists of instructions. "Vibe coding" is different; you're telling the AI to write the instructions and acting more like a product manager, except without any of the actual communications skills that a good manager has to develop. And without any of the search and learning that I mentioned before.

For that matter, a lot of chatbots don't do learning either. Chatbots can sort of search a problem space, but they only remember the last 20-100k tokens. We don't have a way to encode tokens that fall out of that context window into some longer-term weights. Most of their knowledge comes from the information they learned from training data - again, cheated from humans, just like humans can now cheat off the AI. This is a recipe for intellectual stagnation.
