The first paragraph confused me until I read you live in Paris, I assume in or around what they are calling Paris Centre now. Relatively few (3%) Americans live in the sort of density you would find in Paris (25K/sq mi, Commune of Paris, NUT-3 statistical area). Most Americans have the kind of space to allow them to grow their own veg and herbs, or even forge a knife. (Paris should steal an idea from their more enlightened brethren in the UK and offer allotments in urban areas.) Sadly too few baguettes...

Don’t be mislead by US government stats about rural v. urban population. Their definition overstates the number of Americans who live in (what Europeans would define sociologically as) urban areas. I discovered this when I perused a list of US Census urban clusters and discovered Zuñi Pueblo listed there.

I can’t see how hobbyist computing with open source operating systems and legacy hardware will ever go away, and with a thriving community of interest to boot. Analog ports forever and confusion to the usurper Apple slabs...

The convergence (a big fad term of the 1990s) into infocomputotainment will eventually cloy and kids will rediscover the real world, as they did in the 1970s back-to-the-land movement rebelling against conventional TV culture.
