You can define “recursive” as accelerating growth, in which case it remains an open question whether any particular scenario, such as sped up folks researching how to speed up, is in fact recursive. Or you can, as I had thought you did, define “recursive” as a situation of loop of growth factors each encouraging the next one in the loop, in which case it is an open question if that results in accelerating growth. I was pointing out before that there exist loops of encouraging growth factors that do not result in accelerating growth. If you choose the other definition strategy, I’ll note that your model is extremely stark, and leaves out the usual items in even the simplest standard growth models.
