Is an appropriate response to not getting out of touch.
For example you can invest a lot of time in learning some kind of framework and get really proficient. Maybe that opens up new opportunities to you. Maybe in a few years the framework falls behind and you should have better invested your time in something else?
I think you can do a lot of great things without knowing every detail of a black box. And it allows you to spend your time on other things which are maybe worthwhile in the long run.
What's important is that you do not avoid digging deeper into a topic just because of pure habit. Maybe that kind of self-reflection is a trait which is less prevalent in "Expert Beginners" called out in the article.
Every framework gets out of date after a few years. It’s par for the course in technology. You have to ride the hype cycle.
This sounds pretty similar to the exploration-exploitation tradeoff in reinforcement learning (game playing AIs). Exploration comes at a cost, and exploiting current knowledge is safer, but if the agent doesn't explore enough it will have lower total score. A good exploration strategy is a must because knowledge comes from exploration.
In most competitive games with scouting you have to move up the ladder quite a bit to find solid scouting.
