A buddy of mine introduced me to the concept pair of Fluid and Crystallized Intelligence. That's the short answer to your question. An older dev will have more accumulated experience and will be able to make decisions based on experience much better, but a younger dev will adopt new tools and learn new frameworks faster, and the latter tends to be the heavier load for the average job-lifetime (say 2-5 years) in the modern tech industry. |

I don't believe this one second. After you've worked significant time in a multitude of platforms, languages, and frameworks, you tend to notice what they all have in common. Van Neumann architecture is pretty much the same everywhere. The principles of functional programming are pretty much the same everywhere. Very little is new under the sun.
Maybe there's a hypothetical engineer that has spent 30 years doing one thing and has "fossilized intelligence". But I don't think that's the norm, and I'm pretty sure that will show up pretty quickly in an interview.
