Wait, so this object is going to pass quite close to Jupiter, Mars, and Venus? And the Juno probe, which was planned to be decommissioned soon anyway, could potentially be maneuvered to follow and get close to the object? Kind of uncanny and kind of a science fiction plot, but fun to think about.
When he claimed Oumuamua was a solar sail remnant I thought "Neat idea, let's wait for further observation." Then we discovered what it actually was and properly understood how it's shape gave us the reflection characteristics that it did.
He was simply wrong. I didn't think Avi was a crank, just that he put out an interesting guess that happened to further his solar sail work.
