Thanks for the article! While I studied set theory, I’d never had a run through of any of the history before. Like a fine constructive proof, your article makes it much clearer how all the parts fit together into a logical whole :-) It’s depressing to hear how it ended for Cantor. Especially given how modest he comes across in his letters. One thing I’m confused about with the plane to line bijection - how can you be sure you’ll eventually hit another 0? What about .11111...? There you can never switch over to the other dimension and the whole of the .11111 line on the plane will have the same representation, no?
