> and you vaporise the meaning from a lot of people's lives
If the meaning of your life is to obtain a solution to a given problem, then getting the solution would "vaporize the meaning of your life" in the same way as when someone that claims his meaning of life is to raise their children would "lose all meaning of life" when they finally move out and start to successfuly live on their own. Yes, there could be some nostalgia in both cases, but if you are psychologically well-adjusted, the pros would still far outweight the cons, the happiness would outweight the sadness.
