Something like this, where they put up a 30-story building in 15 days in China. Super impressive timelapse: [this video]

Actually not BS, see the Broad Group's web site and their timelapse of the 'demo' project [1]. They don't count the time to put in the foundation and drive the pilings, just the erection part. That part consists entirely of lifting pre-fabricated sections in place, connecting pipes and wires, welding to the rest of the building and moving on to the next one. [1] [this video]

This format is painful to read, so I'm copying the content here. This is a series of tweets by [LINK] -- If you are using software to go after a legacy physical vertical, we are most excited if you do it "full stack" [0]. With @counsyl, we found that one cannot live by bioinformatics alone. So built a full clinical lab + software + national salesforce. Here is a video of our robotic genome factory: Also: insurance coverage, clearances, clinical integration... [1] The reason to do full stack is that it's hard to replace just one layer of an outdated legacy stack. CAC & integration costs can kill. For example, consider "restaurant powered by technology" vs "tech for restaurants". With code, re
