Visions of future past reviewed

Let's review our progress as anticipated a century ago.

1) A robotic barber. Nope, don't have those.
2) A battle Zeppelin. Nope, don't have those.
3) Aerial intracity taxis. Not quite yet, and if and when we do, they won't look like that. And we definitely won't launch aircraft with wings as the primary means of lift by dropping them off a platform about 3 metres off the ground.
4) Ariel postmen. No, and winged aircraft can't fly that slowly.
5) Errr... riding undersea, giant (robotic ?) seahorses ? Umm, no. Very no.
6) A roomba. Yes ! Though they look a bit different.
7) Umm... errr... going diving and throwing fishing lines through the surface of the water to catch seagulls. No, and... why ? Just, why ?
8) Using a birdman suit to arrest misbehaving pilots. Not quite, though this is surely even better : https://www.youtube.com/watch?v=_VPvKl6ezyc
9) Manned surveillance drone. Almost !
10) Some kind of super super super fast egg incubator ? No, because that's not how eggs work.
11) Using wing suits to battle giant eagles and steal their eggs. No, for lots of reasons.
12) Racing giant fish underwater. Srsly.
13) A robotic orchestra. Well, sure, I guess.
14) A mobile home. Yes, but not this literally.
15) Feeding books into a machine and turning a crank that turns them into sound delivered via headphones. I guess... kinda ?
16) Robotic beauty parlours. Nope.
17) Armoured cars. Yes ! Though it's not typical to ram your opponent.
18) An aerial bomber. Yes !
19) Underwater croquet. Well, it's not mainstream.
20) A whale pulling an underwater tour bus. Umm, no, but I want one.
