We, the rich, will remain in denial and/or inaction for as long as we can - i.e., for too long.
That's why I'd try and focus on a few things:
- Reduce the gap between realisation and effective response. Reduce friction for speedy adoption. With simple tools that use local resources, practical documentation, and open licenses.
- Create slack. Or at least recognise existing slack.
- Decouple vital systems from each other. Not everything is equally important. At the very least, do get a crank-charger for the phones of people who repair energy supply.
- Think about "serious worst-case". Not like a sissy, but like Mercedes Benz engineers think about airbags.
