It’s one man only, and he probably has other things to do in his life.
Ok but... if this is the kind of problem that can be done faster by adding people, why doesn't he get a team, like Eiffel did?
It's a hobby, not a worlds fair exhibit...
If you have to ask, you will never know.
It probably took you 20 seconds to write your comment; why not hire a team of people to divide up the typing so you can get it done in three seconds?
You assume efficiency is the goal.
Because its a single person? possibly in his free time? the real one took many fulltime builders
I think it's 8 calendar years between starting and finishing, not 8 man years of effort.
Also Gustave Eiffel didn't build the original by himself.
Yeah! And this one's only 24 feet tall; the real thing is at least twice as tall.
what is this a tower for ants?
I was going to make a joke about different safety standards over a century ago, but then I discovered that no one died during the building of the original Eiffel tower. Color me impressed!
