What would be really hilarious is, I think that would allow her to serve two more 4 year terms after her 2025-2029 term ends because she would not have run as President the first time.
That's incorrect. The 22nd amendment states: "no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once". So unless Biden would wait for at least two years before stepping down, Harris could only be elected for one more term.
To be fair that's mostly a case of "even a broken clock is right twice a day". Psychology was still in its infancy back then and they had so few ideas how to actually help people that insulin shock therapy and lobotomy seemed like good ideas. When looking at it with modern knowledge it's easy to say they already knew when pointing at the bits of decent ideas back then. In reality that's cherry picking between the heaps of wrong and outright dangerous ideas prevalent at the time.
