I noticed a sharp decrease in my world curiosity at 34. This was also the time in life that I accepted a lot of "responsibility" towards the traditional way of life, ie, stable well paying job, career growth, long term relationship, etc.

My read is that once you are fully integrated into the "system", it has micro ways of keeping you engaged - working towards that next promotion, buying a new model of your favorite EV, having your stocks vest so your net worth can increase, etc.

Creativity requires freedom to take risk. Post industrial revolution life incentivizes you to not take risks. Overtime, variability of actions goes down as does creativity.

Our jobs are all consuming of our lives - we see it as a moral good to see our jobs as "crafts"; so if you want become a better X, you should not only invest your 9 - 5 in it, but also your weekends reading books about it, your free time doing side projects showing your "passion", found a business so you can ascend into a new social class of "founders", etc.
