Yeah, he’s hypothesizing that sometime in the future some magical AI (that doesn’t currently exist) will know each of us so well that it can predict how each of us will vote, and thus alleviate us of that burden.
The part that is creepy is that he seems giddy at that eventuality.
Elections are like measuring the temperature of a sample by measuring the energy of each molecule in the sample. However, there are other ways of measuring temperature that don’t require that detailed information, and they are the ones actually used.
Many elections don’t provide any information not already known by the polling organizations. If the gap in the polls is large, 10 or 15 percentage points, it is very rare that they are wrong.
Lots of elections are essentially useless. For example, there is no reason for Wyoming and Vermont to hold presidential elections. Each states 3 electoral college votes will go to the Republican and Democratic candidate respectively. In the rare case where they would not, the winning candidate would have won a huge landslide in all the less partisan states.
The uselessness of elections is also recognized in many local races, where one party or the other simply does not run a candidate.
