Laser leads to Fiber Optics (SS Cockpit) and Fusion (SS Engine) but it appears that we could research Computers instead and still get both of those techs. I think I only put one turn in it, so it wouldn't hurt too bad to switch. We will also need Superconductors (SS Thrusters) and Genetics (SS Stasis Chamber). So we need 4 techs for our ship. Two of them require at least one more prereq, either Computers or Laser. I think Computers also gives a discount on the latter two techs, so it might be a better idea to do Computers instead of Laser. Joao will give us Computers for Satellites and 2200 gold, also something to consider if we want to focus on only spending our research on actual SS techs - perhaps putting a turn or two into Computers would cause him to lower his price. Qin will give us Computers for Composites, but I don't know if that is a better deal or not.
