That's fairly absurd on its face.
There are many important predictions to be made about medium term outcomes (say, in the 5-25 year range).
If someone says "We will never develop grid-level energy storage because elves cannot fly, therefore renewable energy is hopeless", we don't have to wait one second to investigate and (in)validate this claim.
If someone says "Sea level will drop by 3m within 15 years because today's cows are farting less", we do no thave to wait 15 years to investigate and (in)validate this.
If someone says "Astronomical body N28291k will hit the earth at 13:45 on Dec 2nd 2037", we do not need to wait until 2037 to investigate and validate the claim.
If someone says "The cost of coal will decrease by 20% over the next 10 years", when all known reserves of coal are more difficult to access than historical ones and when demand for coal appears to be dropping, we do not need to wait 10 years to investigate and (in)validate this.
