Yeah your right about the handmade arena alright - I think also, in small towns, or places out of the ways, like the town I grew up in, it will take a while for the AI to affect their way of life there - apart from AI farming maybe, but most likely that will be larger farms.
About pulling things down and fixing it - that is a good job that you will be safe with. There is a lot of skill that goes into the fixing etc., also tearing things down seems cathartic - its like the ending of Office Space. I hope one day after all this, to get a job outside - if there are still jobs for me then as everyone will be wanting the safe jobs etc.,
Thanks!
