Woah, this seems far-fetched. But I have checked on the Wayback Machine and get the same result.

Dominic Cummings said in today's press conference that he had written last year about coronaviruses. But the internet archive suggests that the only reference to "coronavirus" on his blog was added sometime after March 5th this year (to a post first posted in March 2019).

I would not jump to conclusions. But it is very weird.

It's definitely not how super-forecasting works https://www.bbc.co.uk/news/uk-politics-52800595

Is it plausible that on April 14, the day he returned to work in Downing Street, Dominic Cummings edited an old blog to add a seemingly prescient reference to coronavirus? https://twitter.com/swiftonsecurity/status/1265002459069648896?s=21 https://twitter.com/swiftonsecurity/status/1265002459069648896
