I find it hilarious how much religion is put into Gnome vs. KDE in this case. I did use both. I honestly have no strong favourite. After that many years of Linux desktop environment DE hopping I came to the conslusion that the DE should get out of your way and allow you to focus on your work.
Both Gnome and KDE support that. Actually Gnome a tad better as it gives you less knobs to turn an waste your time. Accept the defaults and if defaults are bad move somewhere else.
A delicate topic with many perspectives. Our small families make it possible to devote so much energy to our kids. However autonomy is all so important to become a strong adult later. We deliberately need let go more than we do now.
As you mention Lafarge. I think his fallacy and other theorists of its time and school of thinking was mankinds natural sense of enough os enough.
Lafarge wont come true with the quite large inequality of wealth and mankinds appetite for disteactions and general fear of silence and deep contemplation.
In the case of Europe much of generated wealth is wandering abroud (China: goods, US: digital services) so wealth doesn't get enough redistributed but is created somewhere else.
The dispora means little though, the people in the country count as they live 365 days there without the convenient ability to comment from a distance and they are ones who would have to die for a turnover.
Space is cold but has little mass. Either heat can radiated or transfered. To transfer heat, mass which easily absorbs heat is required. The moon might be suitable for that.
