The biggest obstacle to any robotic automation will continue to be trade unions. Most people want that more or less guaranteed lifetime job which barely exists anymore anyway. Most of the people I have ever known can't conceive of being proficient in more than one field. Happily this forum is full of individuals who are multi-talented.

An historic example, Byckminster Fuller's Dymaxion Bathroom, killed by the plumbers.


https://blogs.uoregon.edu/dymaxionho...xion-bathroom/
Quote:
The Dymaxion bathroom was comprised of four stamped sheets of metal or moulded plastic which could be bolted together by section and was light enough to be carried by two workers. [1]. Forget about a messy installation process, all of the appliances and plumbing are built in and one only needs to hook it up.
....
The Phelps Dodge Corporation was to produce the bathrooms but they were met with resistance from plumbers fearful of losing their jobs and so the bathrooms were never produced.

If you want a life time job security get one in robotics, automation or just fixing other peoples mistakes.

"If you want a life time job security get...." over it.

I knew one person who retired at 65 from the only job he ever had. His name was Percy Zumwalt.

Yeah, I'm in IT and dabble in electronics/robotics, but I hope even much of that can be automated. Although I enjoy the field, I wouldn't mind if my job were obsolete and I were challenged to learn something different. Might even be the kick I need to pursue one of my many entrepreneurial interests.

Asphalt shingles should never be adhered to the roof sheathing. Firstly, they have a limited service life, and must be replaced fairly regularly. Secondly, rigidly adhering them to the a dissimilar substrate will cause failure due to differing rates of expansion and contraction from the large temperature changes that a roof has to endure. This is also why trying to use patching cement to flash in around roof penetrations doesn't work either. Everything has to be able to move a little bit

I'm a roofer/carpenter btw, and most homeowners know absolutely nothing about how their home works.

I went back through the thread to find Permalink #18 as your referent.

Asphalt roofing costs US$4-7 while the non-solar Tesla tiles cost $11. Considering the service life and airborne debris penetration resistance, why would the homeowner be considering asphalt.

This may change, Tesla have introduced a v3 roof that uses horizontal arrays instead of the vertical tiling system they had previously. Cost for the solar part is reduced as well.

I know I'm never reroofing or building a house with asphalt shingles ever again.

I wish I could say the same.
