Time it consumes is a lot. Like you would be struggling otherwise. Some of the time consuming actions happen because knowledge transfer does not happen. I know I had to learn from a lot of mistakes and nobody explained things. It would have saved a lot of time. I also think that with time the truth changes and we move ahead based on new change in the world.

Yes. In societal terms, truth is far more fluid. In natural terms, quite static, but there is the possibility for change.
