You tried to use one expert as a refutation of my claim that there was a general consensus with how long it would take for computers to beat a human in Go.
A simple search on google will provide you with plenty of writing backing that sentiment up.
Asking any of your friends who took AI classes back then would confirm the same.
Of course there were people who believed that Go would be able to beat humans. Just as today there are people who believe that AI can be a treat.
But it wasn't a majority of people who believed Go would be able just as it isn't a majority who believes AI can be a threat.
I.e. just because the majority believe something doesn't mean it will be so (or vice versa)
And not media reports from present-day that just repeat this meme that almost everyone believed Go wouldn't happen for decades.
A highly prominent expert opinion but the general consensus was that it would take a long time. Ask anyone who went to AI class back then.
Here is another expert
"In May of 2014, Wired published a feature titled, “The Mystery of Go, the Ancient Game That Computers Still Can’t Win,” where computer scientist Rémi Coulom estimated we were a decade away from having a computer beat a professional Go player. (To his credit, he also said he didn’t like making predictions.)"

You also find highly prominent expert opinions that AI is going to be dangerous and experts who don't believe it. Most people don't believe it, most people believe robots wont take jobs either.
And no I don't need to provide you with anything since you have only problem my point that most people didn't believe it would happen which is why you didn't link to anything saying that most believed it would happen.
