The problem with your argument is that there are other diversity initiatives in the programming world which are mainly gender and race focused. That is undeniably true. There hasnt been the same thing at the same scale for older programmers. In fact there have been many articles on this very forum about how many tech companies filter out older engineers when searching for talent. Its not the first time this topic has been brought up. IBM was actively phasing out older workers and long term workers. Lets not act like data isnt there to support the claim even if it is just anecdotal.
