I think it's more like a case of continuous improvement. After every election, things should be examined for ways to make things better. After a close election, more people will have concerns.
One thing that amplifies suspicion this year is the fact that it took so long to count the votes, and the nature of the votes this year practically guaranteed lead changes in the reported voted counts. In most states, the absentee ballot system was designed for a few thousand votes, and it had to handle millions this year. Even without Covid, I think there will be a big push to have more mail in voting in the future. So, states should look to make sure that they have a robust system that can count those votes quickly, so we don't have those dramatic lead changes that took four days to count.
But, to Darat's point, you don't want to fall into the trap of trying to make things better in order to address the big problems we saw this year. We didn't see big problems.
