Arthur C. Clarke predicts the future (1968) [video]

Like Steve Martin, this man barely aged after a certain point. You can see footage of him from the eighties and nineties where he looks much the same.

* Cities: By rights, he should be correct about cities, but instead humans are all being forced into cities even though there is no particular need to.

* Planetary engineering: We seem to be able to change the environment of this world but are nowhere near doing it to other ones yet.

* Primates: Nowhere near that one.

* Replicators: nowhere near this yet.

* Suspended animation: I have heard this discussed for decades but AFAIK no one has managed to achieve a decent version of it.

* Telecommunication: largely correct.

* Transhumanism: he talks about the evolutionary potential but not about the potential costs, or how certain forces could use it to control others.
