>> We find that the introduction of the new composite racquets temporarily helped younger players at the expense of older players, reduced the rank correlation in player quality over time, and increased exit rates of older players relative to younger players. We find that these effects last for two to four generations of players.
Pretty cool, fun, interesting study. I hope the authors leave it to the reader to make sweeping generalisations/extrapolations from their results. (Still reading.)
Edit: generalisations are pleasantly restrained. I found the supporting statistics much more interesting than the mathematical modelling. Maybe I just don't have the patience for the latter, but I'm not sure it really lends more credibility to the study's conclusions.
As the natural selection gets more brutal, new players have to develop new, more effective skills to succeed.
I wonder if there are startups or programs from institution with a focus on this. I am aware of a popular course "Learning How to Learn" on Coursera. But it seems like an app that interactively helps people to apply this sort of lessons on a concrete set of materials (e.g. Finance, Cardiology, Microprocessor Design, Software Design, etc.) would be even more useful.
Why not teach the same number of people to be 10x? ;)
Technological change in the workplace almost always refers to technology that makes a worker more productive. Since the demand for most things is constant, this means you need less workers for a given product. So, the problem would not be old workers being worse at their jobs - the problem would be that, absent external factors, there would be less jobs around.
