That is the difference today. As you said lot of things you learned decades ago is still applicable knowledge. The AWS ad-hoc stuff we learn today will be outdated and mostly useless information very soon. The undelying principles (even distributed computing) we already learned years ago.

Both.
- As we accumulate knowledge while aging it becomes more and more difficult to learn new things. We are smarter and smarter though. (Most of us :)
- Losing interest sooner is natural. For example by the time I read through the documentation of one service that deploys containers on AWS the information is already outdated and two other, newer AWS services released doing almost the same. When someone says: "we need to investigate this new AWS ..." I am already shutting my ears.
Let's say you are not CTO but developer, and your CTO is 32yr old. Would you be as happy?
