San Fransisco was not an attempt at greater legibility but an an attempt to rationalise the vector point count of the font to make it run better on sub optimal systems with poor graphics (Apple Watch), if you work with vector images and bitmap images (a pro user) you will immediately grasp the truth of that. As to custom GPU's all that brute force the other operators have packed into the manufacturers of their product may seem wasteful compared to Apples more streamlined approach but it is precisely that brute force that pro users seek in their GPU's for day to day intensive tasks in their pro apps that non pro users never use. None this would remotely matter if Thunderbolt had parity of speed with with the systems mother board and could talk to the processor at that speed, then whatever smoke and mirrors Apple employed to give the illusion of extra speed would be circumventable  by the the pro user who would be free to choose from the free market whatever solution suited them best.
