PCREs are Perl Compatible Regular Expressions, they have backreferences and other constructs. Almost all languages that have Regular Expressions have similar constructs. "Computer Science" Regular Expressions are more limited and implement a "regular language" as defined in https://en.wikipedia.org/wiki/Chomsky_hierarchy. This gives some guarantees, which go out the window with PCREs.
It is not Maslov, but Parasuraman[0] for automation and decision selection:
1. The computer offers no assistance.
2. ... offers a complete set of actions.
3. ... narrows the selection down to a few.
4. ... suggests one alternative.
5. ... executes the suggestion if the human approves.
6. ... allows the human a restricted time to veto the execution.
7. ... executes, then informs the human.
8. ... executes, informs the human when asked.
9. ... executes, informs the human when the computer decides to.
10. ... acts automatically.
This is a framework for more than user interfaces, but it comes close.
This is a nice concept. In populated areas there is quite a bit of pushback from the population to install wind turbines due to the distracting movement of the blades and their shadows. This idea solves that nicely by hiding the turbine. Maybe the marked for this is densely populated Europe?
I feel like this is worse though, as a tower like that looks million times worse than a wind turbine. I would hate if structures like that started appearing across the landscape.
We already have square structures in the landscape: office buildings. These could be put on top of regular buildings keeping the shape of the buildings, just making them a bit higher.
