You disagreed that 2047 was reasonable on the basis that researchers didn't think it wouldn't happen in the foreseeable future, so your definition must be at least 23 years for consistency's sake
I'd be OK with that, too, if we adjusted the bet for inflation. This is, in a way, similar to fusion. We're at a point where we managed to ignite plasma for a few milliseconds. Predictions of when we're going to be able to generate energy have become a running joke. The same will be the case with AGI.
