I think it is very realistic, I started mine off early and they seem to start to really take to it around 4-5. The point is not to get them to follow in your footsteps, but rather to open their minds to how logic makes them think different. The funny part about logic, is once mastered, it transitions a person from learning resistance, to craving learning. One of the best ways to teach logic is via computing. I have seen the transition in my boy and it is great. I don't expect him to be a developer and would be happy if he decided to go into something other that development but their is no denying, knowing logic buts him at a significant advantage over the majority of the population.
