There's sort of a bottleneck in the tech tree where you have to learn either automobile or flight. If you choose automobile, you can go around flight to learn mass production and computers. You can hold off on mobile warfare until after computers, and then you can get robotics, but then you're stuck with virtual dead ends: labor union, recycling, or nuclear fission. If you choose fission, you can then learn nuclear power and laser.
So, under the right conditions, after computers and before flight you should be able to learn mobile warfare and robotics and the fission-nukes-laser series and labor union and recycling. However, this is subject to the rules on which techs are available on a given turn. If you learn those rules and plan carefully, I'm sure you can get a few techs during the period when you have Colossus, SETI, and superhighways all working for you. Shouldn't take long!
