It's that thought that I believe fundamentally for humans, change can be very difficult because our bodies are hardwired to crave predictability. I know how that thing works. I know how that thing wears out. I know how to fix that thing. I know who to call to fix that thing... And so the thought that we would pick something that we haven't seen before, we haven't tested for 10 years personally, we don't know how the sand on the salt deteriorates it. We're not sure if the company we usually call the fix, it we'll be able to fix it. It's hard to choose unpredictable. https://www.solvecast.com/articles/detail/29674-how-fear-of-change-inhibits-our-progress-toward-a-sustainable-future-with-laurie-mcginley
