Dude, who even knows.
Found another thing that the new personality has innate skills at plus I still have the developed abilities the old personality compensated with: somehow the stereoblindness resulted in an inability to compose a complete 3D mental map of an area and instead I developed by-“scene” local maps but an iffy sense how they connected and some really powerful dead reckoning, that I mentally kept track of how far away things were and in what direction and could use that to retrace my steps for as far as 15 mi (I found when I started tooling around in the car) or navigate blind through unknown territory to a known destination on the other side
Anyway I went to the downtown Apple Store to get my phone glass replaced from when I fell down on it with my keys in the same pocket, and wandering around waiting for it I found I could do both now and it makes for very powerful orienteering
