Ask HN: Geoffrey Hinton and the Loch Ness Monster

One week ago, Geoffrey Hinton posted on X about the Loch Ness Monster. I thought that there would be a follow up with more explanation. I am unclear on his intent. Was this an actual sighting, an explanation of an illusion which appears like the Loch Ness Monster, did someone hack his account, or was Hinton posting under the influence: https://x.com/geoffreyhinton/status/1729247583061553361?s=20
