The OP didn’t make any arguments about the health risks, so one cannot infer his stance about long covid from the post. As I intimated in my comment, I don’t think omicron is as bad as flu, I think it is as bad as a cold. Yes, I would attend if there were a 20% chance of getting a cold. The additional covid risk makes almost no difference to the background risk of attending the conference and is swamped by other risks, such as the risk of a nuclear strike on London or being in a traffic accident on the way to the venue.
