When a prediction has a probability attached to it, it should be possible to check the math. In some sense it isn’t really a prediction about the future, so much as a statement about current information (which is not complete).

Or, possibly, they are using “90% confidence” colloquially as “pretty sure.” If so, that should probably be made more clear. He’s using the fact that the researchers agree as an argument from authority, which is doubly wrong if the apparent authorities here were just giving their hunches.

It’s a quote, and you are gonna laugh when you find out who said it.

Attributed to Yogi Berra, I just don’t think it fits the situation here very well.

We are quite clear in the abstract and the paper that the predictions are conditional on the continuation of the smooth progress seen to date. Contrary to the GP's interpretation, these predictions are holding up well.

"When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong."
