Lots of groovy motors in lots of groovy places definitely provides advantages - blown flaps allow a lot of lift and a lot of efficiency but are also mechanically complex. Although the A380 apparently has blown flaps, previous attempts have been cumbersome. I think we'll see the most advances in small-hop aircraft... like the 787, which Airbus has no competitor for. Hopefully they aren't seriously relying on: 'cuz holy fuck, Airbus.
superconductivity, a phenomenon that removes electrical resistance when certain materials are cooled below a critical temperature.
That part jumped out at me too. They may as well have said commercial scale fusion reactor. High temperature super conductor that could be deployed at scale would win you the Nobel prize in about five minutes. Those "medical scanners" they reference? Yeah, they're liquid helium cooled to like 4 Kelvin.
Hybrids are most likely going to be a big revolution - but honestly, unless there's MAJOR strides in the domain of electricity, a purely-electric large-scale trans-sonic plane like the 747 or 777 most likely could not happen. For that to be possible, one of two things would need to be accomplished: an electric jet engine (which would require an insane amount of electricity most likely) or trans/supersonic propeller propulsion (which I THINK has only ever gotten close to in WWII's fighters like the Mustang - and even then, it was still 200km/h slower than a 747. But maybe, just maybe with modern aerodynamics (and our understanding of aerodynamism/fluid dynamics at transsonic or supersonic velocities) it would be possible)
