Don't be too worried about it.

1. Manual coding may be less relevant (albeit ability to read code, interpret it and understand it will be more) in the future. Likely already is.

2. Any skill you don't practice becomes "weaker". Gonna give you an example. I play chess since my childhood, but sometimes I go months without playing it, even years. When I get back I start losing elo fast. If I was in the top 10% of chess.com, I drop to top 30% in the weeks after. But after few months I'm back at top 10%. Takeaway: your relative ability is more or less the same compared to other practitioners, you're simply rusty.

Thanks for your comment, it set me at ease. I know from experience that you're right on point 2. As for point one, I also tend to agree. AI is such a paradigm shift & rapid/massive change doesn't come without stress. I just need to stay cool about it all ;-)
