I can see from those tablets that autocorrect predated writing.
We should not be surprised by this. It’s the way evolution works all the time.
They also reused the tablets and kept them moist, which made corrections pretty simple. When one city-state got pulverized by a none-too-neighborly neighbor, the visit was often accompanied by fire, and as the palace/archives burned down, the tablets got baked and the last things written on them were preserved for us. :^)
