Ok, I concede that, it was exagerrated in what I was reading. What do you think about the other point? Was a computer as we know it today practical to design before the discovery that arithmetic and other principles of math could be worked out using logic?
I'm not an expert (my only qualification is that I read a part of Babbage's book; others must know a lot more), but see http://tomforsyth1000.github.io/blog.wiki.html#%5B%5BBabbage... and (linked from it) https://www.fourmilab.ch/babbage/cards.html — it looks like he did have a reasonable design of a computer in fact. (Except for the too-many-digits-of-precision thing, that the OP tweet thread is about.) He seems to have well understood how not just arithmetic but a lot more could be done mechanically.
