1. I think almost all of it would blow me away. 20 years ago I had just gotten onto the internet where if I was lucky it'd take 60 seconds to dial up, another minute to fully load a website, and sometimes all night to download a video or some songs. Now all of that is instantaneous. The ability to do all of that from a device I can carry in my pocket is also mindblowing. Touch screen technology and voice recognition are up there too.
My favourite advancement though is Google maps/Earth/Street view. I was truly ecstatic when I first encountered Google Earth when it came out in 2006(?). It opened up perspectives I had never even considered. I could revisit places from my childhood from the other side of the world, see what was on the other side of that wall I never climbed or what that neighbourhood on the other side of the motorway looked like.
Now I can use it as a tourist in a strange city or plan a route to unfamiliar places or even as a tool to find a new place to explore. It's impossible to get lost now (which can also be a bad thing, so sometimes I purposely don't take out my phone and just let my instincts guide me)
2. I think I've read that the hand waving tech from Minority Report is in the works. That'll be freaky when we're at a point where we take that for granted and don't even think about it.
