I've moved on from science. In my mind I pursued science as a means to provide society options to advance. What I didn't realize is that most of the country wanted to buy condos in Florida at amazingly inflated prices. I wanted to research methods to produce clean fuels. I wound up in an underfunded computational lab. I stayed with it because I thought it would all pan out. Turns out I would have been much better off in an experimental lab somewhere, probably MIT. The reason for all these computational labs is that computers are cheap and grad students are cheap, experiments are expensive. Science didn't work out for me so, compared to my peers, I got lucky and found a pretty good job in a stable company.
When it comes to education I've come to believe that less really is more. I hope that my country puts every penny it can into educating children from birth to 12th grade. I advise my friend's children to only go into science if your professors literally are begging you to go, give you a ton of money and a scholarship to the very best school in the field. Even in that case think very carefully about your assumptions. Even in that case I pray for their sake that they don't take the offer.
I don't think much of science as a means to resolve social problems. I think that society needs to face its problems and solve them directly. Society only looks to science for solutions when it KNOWS it is really desperate. If this country finds itself in a dumb war I think the politicians, the rich people, and the CEOs are going to find a research/engineering job of the kind that have been outsourced for the past 10 years or so for me really quickly. I still hope that doesn't happen because a lot of people like me, including my son, might die in such a war. I think a great deal more of finding a good job, better yet starting a company, somewhere. Buying the smallest, least expensive, and most comfortable house possible. Try to get a nice backyard or, better yet, a fair amount of land. Raise a nice family. Living within my means. Saving for an early retirement. Avoiding office politics. Getting involved in local politics because I think those really count. Don't try to win anything in local politics, try to get issues resolved in a neighborly, sensible way. Trying to live at peace with my neighbors.
