This doesn't make sense - AI is to allow unskilled people to produce what was previously only produced by skilled people.
IOW, how does having 2 years of experience using an LLM to generate code beat having 2 months of experience?
The whole point of using the LLM is that very little skill is involved; how does starting earlier with it provide an advantage? If it's as good as it is claimed to be, starting later with it won't make a single iota of difference to the generated results, compared to someone who started earlier.
