Just my $.02 on the subject..
A week or so ago I was having a conversation with the lead field engineer on a $100M expansion and renovation project we are currently on about how it's really amazing we are able build these projects with the amount of stupid we have to deal with.
This autonomous equipment can work flawlessly 24 - 7 in a perfect environment that's been laid out on a computer screen and meticulously programmed into their computer chips.
Now enter the real world commercial or large multi-family site that changes daily - the bigger the project the more the changes. The reality is the job site is a constantly changing "organism" that the human workers must adapt too and make changes in order to get it completed on time and on budget - hence the conversation with the field engineer.
Humans - even the dumb ones we have to deal with - can adapt, stand there looking stupid, go home or over come the issue and continue on building. How big will the jobsite trailer need to be to fit all the programmers needed for dealing with all the same variables of a modern day job site?
Now I'm not foolish enough to dismiss this technology will never come to fruition as it ultimately will, however I am old enough to know that I will be comfortably sitting in a lounge chair on the Pacific side of some Central American country enjoying retirement by the time this technology puts me out of business.
On second thought renting out fully wired double wide office trailers for the gaggle of programmers needed to run these new autonomous machines might be a profitable retirement business..
