We've spawned a 20% non-GScientist when we were pretty keen on getting a lot of them. One way to catch up is to let the AIs tech the first thing we were going to bulb (Philo) and because we've got a GSpy, use only a fraction of its value to steal Philo instead. The cost is that it is a long time before we get holy-city religious bonuses to espionage. However having an earlier state religion will cost us diplomatically. We can get the 15% state-religion bonus with Judaism in Trojan Horse if we want it and work at it.
If we'd have used our first GScientist to bulb Philo and thought nothing of it, why are we concerned by the idea of instead stealing Philo without religious bonuses for a fraction of the value of a GSpy?
Of all the techs to bulb, Philosophy is a pretty good one. It opens up Pacifism, gets us a religious capital which is pretty useful with 2 great spys, is great for trading, opens up Liberalism, and AI avoid teching it once someone has it I think. If we went ahead and bulbed it, we would be in a position to ignore needed diversions from beelining to UN. We can steal every military and gold generating tech.
Better than Compass or Paper usually. And if the AI gets it first, then just steal it and pocket the Great Scientist for bulbing Paper or double bulbing Education whose universities we get for the hammer costs of libraries.
