And every optimus, in the future iterations will be capable of

controlling CNC machines. Not to the point of designing the rooms,

but to allocate compressed cubes in one designated area for the CNC machines,

and starting up CNC machines to subtract/deduct that mass (from pre-designated

designs) and inserting metal rods, controlling cement pouring mechanism.

Connecting one shell to another...

 

And that would be... Robots building communities in the most remote places...

 

Be it far in the future...

 

The subtractive manufacturing process, it just doesn't have as many

unpredictable steps the traditional construction methods.

 

Of course people will still be needed for overall management...

 

but even processing wood and creating flooring,

waxing the floors prior, or the walls, evenly leveling things out...

 

Possible.

 

I think however, electrical and plumbing will still be done by humans

afterwards. No, that too can be programmed... But within design.
