With the advent of commercial docks at the end of the industrial age, I had just enough beakers to get modern age techs in 4, and I decided that I would try and get the AI to do computers for me as it has prefers that tech above the others and has the most turns for to complete it (together with ecology).
One check on the F6 screen made me throw those plans to the recycling bin, however, as it turned out that computers was my free tech. That did make this age more relaxing to play however, as my scientific ouput increased dramatically again with research labs.
Against all hope, I decided to stall inventing ecology for as long as possible, hoping that due to some freak rng roll, the AI would start researching on it. At this time, they still hadn't invented either Communism, Espionage nor Sanitation, and just completed research on Free Artistry, so my hopes were very low indeed.
On the other hand, I knew the Ottomans hadn't been in their GA yet, and as they were pretty powerful with decent lands, I still had some hope. At the start of the age I gifted them computers and bought them against the Celts, and as I had stopped taking money from powerful AI's when my GA ended, even gifting some of them gpt, I had hopes their tax settings were focused on research.
One turn after I had bought them against the Celts, I decided to do an investigation of an Ottoman city to see whether they had won a battle with a sipahi already, and was surprised to see they were only spending 40% of their taxes to science.

Further investigation of some of the other AI powerhouses yielded exactly the same result, and as I knew they were never going to get a modern age tech at 40%, I decided to give it one final try and give the Ottomans, who were indeed GA'ed, as much gpt as possible.
When I checked on them two turns later, they had indeed changed their science rate!
To 30% science, to be precise....
So, no modern age techs from the AI for me, but they were researching the other techs first anyways. After careful prebuilding of the last 3 SS-parts from Synthetic Fibers, the space ship was launched in 1170 AD.
