Overheard quite an elderly couple debating #AI in a beautiful spot in the #PentlandHills near #Edinburgh. He was all in on the successor species nonsense and she could see right through it. They walked off still talking about it.
The intriguing Castlelaw Hill Fort, high on the eastern flank of Castlelaw Hill in the Pentland Hills south of Edinburgh. Its development began around 500BC and continued for centuries. It comes complete with an underground earth house. More pics and info: https://www.undiscoveredscotland.co.uk/penicuik/castlelaw/index.html
