That is quite optimistic.

  Fusion has been 5 years away for 50 years now, I think that was the joke.

    No, it has been _50_ years away for 50 years. Which leaves room for a joke. "Fusion in 5 years" is either Elon Musk-level of estimating, or Elon Musk-level of trolling.

      I'm sure I heard it as "20 years away and always has been" back in the late 90s. (To me, "5 years away and always has been" feels more like the Apple Glass than Musk: one is endless headlines not actually backed up by anything concrete, the other is just persistently overoptimistic about all timescales by a factor of about 3).
