The longer you live the more likely something will go wrong. That is true but at the same time not all that interesting. Similar problems come up with very young people. Not only can dementia itself exhibit itself in the young, but people can become tuned out to anything outside their interests and expertise and lose interest in learning through play and experimentation. When this happens people become locked in their modes and may not move forward. To add some anecdata I know people who were prolific programmers with perl CGI scripts but were never able to make the jump to modern application programming, not even the relatively easy transition to "modern perl". At the same time I know some older programmers who have contributed to modern apps while working on both embedded devices and machine learning and love being at the forward edge of everything. There are many aspects to work in technology and age is a minor factor especially compared to attitude and interest. This reminds me of how Victor Frankl describes in Man's Search for Meaning that people expected the strong and healthy to endure life in concentration camps and yet many died within days while some who were weak and sick endured because they had something that kept them going through the greatest challenges. Age and experience are factors, but it is how they are framed and leveraged that actually matters.
