Being in both academia and tech long ago convinced me that intelligence is very multidimensional and that smart people can be shockingly dumb in areas outside their core strengths and knowledge. If they think they are smart this guarantees they will be idiots outside their core areas because they won’t make any effort to learn or have respect for other domains. If you think you’re smart it makes you dumb. Arrogance about one’s intelligence also tends to cause age related stagnation. If you think you already know everything there’s no reason to keep learning. I’ve seen 70 year olds learn fundamentally new skills and ways of thinking many times. I’m convinced arrogance or complacency is the root of age related stagnation more than neuroplasticity decline. The latter just means it takes a bit more time and effort to learn, not that you can’t (unless you actually have a degenerative neurological issue).
