Yes. If you're wasting time building UN while I'm building Hoover Dam or Seti,
guess which one of us wins ?

Problem right there. I do not see a generic rate_wonder function, where all
the wonders are rated by the their effects. I.e affects production flag etc.

That's my problem. It should all be in advscience.c.

True. Maybe railroad, bridge building, and airport techs, as well as other
transport enabling techs should have their own handling.

The path I described has never been followed by any AI. I have never seen an AI
select it's highest trade city, build all the science wonders there, celebrate
every turn to pump it to a high level. The Super Science city would really help
the AI.
