Adobe founders were in their early 40's. (born 1939 and 1940, founded 1982.) Also, I really do think that people are aging more slowly, 40 is the new 30 etc.

Also, I really do think that people are aging more slowly, 40 is the new 30 etc. Adolescence is extended; old-age is longer and healthier. But, whether you have an advantage by being older is a question of the value of experience... although each new generation of tech seems to reinvent all the old stuff (so experience helps there), mastery of detailed workarounds is lost. Experience seems to have most enduring value in people and business-related skills, more than in programming. Other things that don't change much are laws and mathematics. Although this doesn't help mathematicians, who need to be creating new mathematics, my guess is that applied mathematicians would get better over time.
