But RMS opinions about Facebook are not extreme, he doesn't propose to refuse to have friends who are using Facebook, for example. He says just don't use it, it's common sense, just like don't eat fast food is common sense. Common sense is sometimes very uncommon, kudos to those who keep their mind clear in our messy times.
(In the meantime, fewer people seem to consider it common sense to be on Facebook, at least it seems to me less and less people are surprised if someone doesn't use it)
Another example is abolition of death penalty in France by Mitterand: right now we French/Europeans believe it is very barbarian to still have Justice use this gothic expedient, and rightly so if you ask me. But just before its abolition polls showed most people opposed the abolition. A new, better "common sense" replaced an old habit falsy believed to follow "common sense".
So back to Facebook: right now most people do not know it, but it is not unlikely that the retrospective "common sense" of the future will be to avoid Facebook today. And I think a much saner regulation on what can be advertised and sold as food to human being in the US will also be retrospective common sense. And not driving cars is also common sense. The list is quite long...

I suspect 'most people' aren't even remotely aware of such arguments. Nor of the effects that choices now will have on their future selves.
Wait, really?
(By the way, leaving a new new Javascript framework does not count, sadly.)
Do you have any proof of this? IMO, the declining birth rate is more of a consequence of a huge number of couples deciding to only have one child (so one child per 2 people -> eventual extinction).

The population of childless aged couples, especially women, is expected to grow rapidly. In Italy and the US, for example, the population of childless women aged 65 or older is expected to nearly quadruple over the next four decades.
