I can only remember 3 things right now:
1 Car technology, the real white headlights and car stereo with Bluetooth hands free for phones, that really make driving more safe.
2 Bluetooth headphones with touch controls, no more need to waste time looking for the right buttons to press.
3 High speed internet, allowing to watch streaming movies in real time easily like on TV, and overall lag free connection to internet in real time.
Do you remember anything else?
I'm from the time before Computers, let alone The Internet.
The most significant development is better home insulation, improved gas mileage and condensing boilers.
That's it.
Everything else is pretty much bullshit.
