I've never heard of this guy before, but this is extremely petty. Are you suggesting you've never been wrong in your life? Do you think it would be interesting if, rather than engaging with anything you said, people dragged out a quote from 28 years ago to dismiss everything you say? This is an embarrassingly low form of ad hominem.

He's basically repeating his mistake - underestimating the relevance of technological progress - from 28 years ago, except now it's explicitly in service of his political bias.

For your information: Paul Krugman is a Nobel memorial prize winning economist. He used the publicity of his award to become, essentially, a political commentator, including an opinion column in the most important American newspaper of record, the New York Times. He's not a random commenter on a website, without any ambitions of relevance. He uses the aura of being an eminent scientist to give his personal opinions a veneer of respectability that they perhaps do not merit.
