Wow! I've seen the future and it works! If this is going to happen anywhere it will be Japan. Though I do see a problem with just going higher and higher, obviously there will have to be some kind of limit or perhaps the foundations get built as if it will be 50 stories right from the get-go.
Interesting, I think when it finally happens, it will probably slightly different than the original concept. It's great to see 3D printing evolving like this though :-)

It will be fascinating to watch as this technology scales upwards. Perhaps buildings (as we know them today) will no longer be built in 1 go and all at once. Soon they may grow as needed! That would make for a very dynamic and cool place!
Buildings that grow :-) As a child of the 70s this is so awesome for me, I used to sit and wonder what life would be like in and beyond the year 2000. I must say, it's living up to expectations. :-D
