While this is a popular sentiment, it is not true, nor will it ever be true.

AI (LLMs & agents in the coding context, in this case) can serve as both a tool and a crutch. Those who learn to master the tools will gain benefit from them, without detracting from their own skill. Those who use them as a crutch will lose (or never gain) their own skills.

Some skills will in turn become irrelevent in day-to-day life (as is always the case with new tech), and we will adapt in turn.
