Not sure about the controlled nuclear fusion, maybe there are some predictions from 1950s available.

Good thought.

In 1958, a Nobel prize–winning scientist from the United Kingdom named Sir John Cockcroft gathered the nation's media to announce that he and his research team had demonstrated controlled nuclear fusion in a giant machine nicknamed Zeta. [...] Commercially generated fusion power was two decades away, he predicted. Just months later Cockcroft was forced to admit that his observation of nuclear fusion and subsequent claims were an unfortunate mistake.
