Wow. One can construct something on paper without actually building it, but since you’re content to argue, I expect no less than you now arguing on the semantics of “to construct”. I’ll discard the troll implication as immature, since this is “Hacker News”, so I can’t say I’m surprised.
Here’s some documentation https://en.m.wikipedia.org/wiki/Babbage_Machine
Feel free to provide year the machine was actually completed by Babbage and Lovelace. A photo or two would be nice.
Trolls these days are still cute to their mothers.
