The decrease in astrology's visibility (people no longer read magazines, and "horoscope blogs" don't seem to have become a thing) may just have led to most young people not having a clue and assuming astrology = astronomy.

Sure, "spot on" is obviously stretching it, but considering the time scale I think he did really well - I doubt anyone today would be able to predict 2064 equally well. Some good examples from the original article:

State of robotics: "Robots will neither be common nor very good in 2014, but they will be in existence."

State of space exploration: "By 2014, only unmanned ships will have landed on Mars, though a manned expedition will be in the works."

Smartphones: "Communications will become sight-sound and you will see as well as hear the person you telephone. The screen can be used not only to see the people you call but also for studying documents and photographs and reading passages from books."

Fiberoptics for data transmission: "Laser beams will have to be led through plastic pipes, to avoid material and atmospheric interference."

Flatscreens: "As for television, wall screens will have replaced the ordinary set."

Slightly too optimistic on the proliferation of programming skills, but remarkable considering the state of computers in 1964: "All the high-school students will be taught the fundamentals of computer technology will become proficient in binary arithmetic and will be trained to perfection in the use of the computer languages that will have developed out of those like the contemporary "Fortran""

It means the rollout in France is much less newsworthy than it seems, though. I get a symmetrical 100Mbit connection at home for about the same price quoted in the article, and this sort of service has been available around here (Norway) for a couple of years, and for even longer in Sweden.

In theory there's a bottleneck in the single gigabit fiber link leaving my 64-apartment condo building, but most of the other residents have opted for cheaper 2.5Mbit or 10Mbit connections, and of course people rarely even use all of that, so I'm able to routinely use my full bandwidth of 100Mbps.

It's also been determined that the discussion in a typical Slashdot story compresses to less than half of a percent of its original size.
