Which these stem cells, if they pan out, very specifically fix
I have never seen someone which is left on the political spectrum at 30 become a Keynesian by 50.
I know such people exist, but they are the exception.
Personality psychology shows personality does not change much after 30.
And there is even some theories such as the “impressionable years” (15-25) which are even more extreme in that respect, stating that basically very little changes after 25.
Overall this makes me doubt stem cells can change any of this.
But I am myself way past my impressionable years, my mental flexibility is lessened, I may be wrong and not open to new ideas.
It would feel sad though, having civilisation lead by the same people over hundreds of years if not more, somewhat stratified, predictable, dull.
Also I really dislike the categorisation into scientists and non-scientists, this really makes science sound like a dogma. I prefer inventors, pioneers, or simply curious people.
