> Is it reasonable to assume that the natural decline in cognitive performance over time is offset by the gains in experience and expertise?

Maybe up to a point. Most of the tools and languages I use daily are fairly recent, or at least new to me. I don't have much of an advantage, if any, compared to my younger colleagues.

There are certainly things I do better now than 10 years ago but I think I'm slowly declining though. Fortunately, there's more than one way to be productive professionally so I hope I can keep up for a few more year.

State of the art tools and technologies today are implementing the features of cutting edge languages and technologies from decades ago.

There are very few capabilities in mainstream languages today, if any, that weren’t available in Common Lisp back in the 1980s or 90s.
