I think you are right. Besides this "Best" category is also fluid. Best of 2000's is not best in 2020s for a business.

This also works as price discovery mechanism for both parties. Best employee can take a break and apply later for different job, profile, growth industry etc. Companies also find better to hire what they think best at market price instead of honorary best which are there for long time.

The last ms team I was on before I quit changed quite a few over the years as the business and requirements changed. I learned a lot about what I enjoy and where I thrive. Where I had done well for a few years the business had become something that was better suited for others. It was best for me and the team that I left and they find someone better suited for the current and future work.

Even now with agentic work there are areas I am able to do well and some areas im not. It's definitely always changing.
