I remember thinking in 1980s that year 2000 would be something unrecognizable. You can feel this optimism in movies like Back to the Future, Blade Runner, Terminator or Escape From New York. They would set entirely different worlds in relatively near future, largely due to expectations from then recent technological change rates.

In reality (aside from tremendous change of political landscape) the 80s and the 00s weren't particularly different to live in.

The ability to have all information at your fingertips everywhere is a big big change.
