I am pretty sure that modern archeology agrees with you in at least some ways (know an archeologist, not an archeologist). I don’t have any specific evidence for mammoth trapping but there are these really interesting stone funnel traps that were used to trap gazelle herds …blogspot.com/…/ancient-gazelle-killing-zones.htm…
Also consider how long humans have walked the earth as hunter gatherers. Agriculture goes back to around 10.000 BCE. The entirety of time between 300.000 BCE and 10.000 BCE was likely (mostly) spent as hunter gatherers. Imagine in how many ways local roles and culture could have differed in that time!
I hear you I hear you. Whenever people ask me about my device I usually tell them that you just exchange the windows problems for linux problems. I don’t mind fixing things as much because the device really feels like my own so I am more forgiving than I was on my other devices. Don’t know how that is for other distros since there are so many but in my experience but yeah I’ve lost count of how many times I’ve had to repair my bluetooth audio.
You could go with an DS1339 which is an RTC with two programmable time of day alarms. If you only need timing you might as well do that. But if electronics isn’t really your thing then just add a bigger battery for the attiny85, make sure to run it at it’s lowest clock speed.
