Hahaha. Yeah, there were at least two scenes where I couldn't work out a better solution than that... it worked pretty well generally. But it was mindbendingly difficult sometimes to logic the simplest stuff, which did impact how I saw disability friendly stuff.

But my point is, it's not a bad method, in a hierarchial society with labour cheap. Just as we had audiobooks for 4000 years - they were called scribes and secretaries (or young relatives)

Back when I was teaching I borrowed 15 wheelchairs and had my class spend the day in them, in Stockholm city, in pairs, to write pieces on the frustrations they faced, etc.
