Thanks for introducing me to the term "half-life of knowledge". > An engineering degree went from having a half life of 35 years in ca. 1930 to about 10 years in 1960. A Delphi Poll showed that the half life of psychology as measured in 2016 ranged from 3.3 to 19 years depending on the specialty, with an average of a little over 7 years. This is very interesting and makes me wonder what it is for tech careers, e.g. web devs, data scientists etc.
