You know, I lived there for about a year, and now my daughter lives there.
It's a damned inconvenient city for modern life, but it's impossible not to love it.  :)
We are grateful to the germans, hollands, italians and other countries whose people participated in its creation a long time ago.
This is our part of Europe.  :)

I am very sorry that this was created for war, but it is very beautiful and technologically advanced. The most amazing thing is that in our country they make great planes, but very shitty cars.

Humans can create incredible things and then find innovative ways to kill people with them. It sucks.

Unfortunately, this is the case. I would very much like these aircraft to have no weapons and perform aerobatics for the public only.
But what can we do about it?

Your English is fine.

Actually, we're cooperating a lot these days, far more than most people realize.

Especially in space. "we come in peace, for all mankind"  These accomplishments are real and we all are justified in being very proud of them.

Global navigation systems are now a big part of our lives. And extremely useful. They are even more accurate when multiple systems are combined. Those drones are positioned using GNSS systems like GLONASS and GPS.

The position and orientation can be controlled to an accuracy of just a few cm using GNSS systems, so they can also be used for lots of things including as you mention, rapid automated construction using rotorcraft designed for lifting and manipulating large structural elements in buildings. The progress could be very rapid, compared to the conventional method, and it would be safer. This will likely become the preferred way of building rapidly, eventually.

Buildings main frameworks could be hoisted into place and then locked together. Large portions of the process could be automated.

Hopefully we wont have huge wars any more, because they would simply be too destructive. Nobody would win, not even remotely.

The civil defense efforts of the US hit a brick wall during the 1980s when they realized that nobody in cities would survive atomic warfare, because the fires would burn so incredibly hot that it bould burn up all the oxygen, and the land would be so totally contaminated from plastics as well as radiation, so much as to become virtually impossible to live on for a very long time.

Also, robots don't function properly in high radiation conditions. It plays havoc with electronics, making cleanup difficult and dangerous, even for robots.

Making it unthinkably wrong.
