If we were to list the mathematical and scientific discoveries

how many would have been done by someone at the age of 50 or
older? How many milestones in computing history were achieved
by someone 50 or older? How many were done by someone over 40?
And I think most of the aging process isn't even quality (what

about quantity of thought than quality.

I'd be swayed if you could link to interviews with older
scientists, mathematicians or computer scientists who said their
work declined with age because they became disillusioned or they
ran into social conditioning issues.

Rather than the two of us expressing opposing opinions and you
loling, we should probably look at research on the matter.
Unfortunately, there is some disagreement with regard to
cognitive decline. Some see it as a gradual decline from early
adulthood and others seeing the decline postponed until later in
This paper titled "The myth of cognitive decline"
actually appears to acknowledge and accept that speed of
reasoning declines with age:
"Findings from a range of psychometric tests suggest that the
rates at which the mind processes information increase from
infancy to young adulthood, and decline steadily thereafter
(Salthouse, 2011). Increasing reaction times are a primary
marker for age related cognitive decline (Deary et al,
2010), and are even considered its cause (Salthouse, 1996), yet
they are puzzling."
but then attributes it to the brain having to deal with more
information rather than having a slower processing speed - a
bloated registry, if you will.
"However, age increases the rage of knowledge and skills
individuals possess, which increase the overall amount of
information processed in their cognitive systems. This extra
processing has a cost."
But an employer wouldn't care if an older worker was thinking
slower because of physical decline or because they had to sift
through more information.
