My house is also built from concrete blocks, because they have quite good parameters when combined with good thermal insulation. Concrete walls were something like 3% of price of the house and they were done in a week, that is again something like 5% of (my) house construction time.

Concrete blocks can be produced locally with rather simple tools. It also has benefit that it may provide work to local people. In poor regions, labor is cheap and creating workplaces is always benefit to local commnunity, so I wonder if automating this out is positive thing at all. I'd like to see comparison of costs/benefits for houses built like this vs more traditional construction. Don't get me wrong, I love tech toys, but this looks very much as a solution looking for a problem.
