I have a new article up on FastCo.Exist provocatively titled “Future thinking isn’t about the future, it’s about the present”. Of course, it’s about both but editors do like to grab attention with extreme-sounding headlines.
For millennia, we’ve grappled with “things” pretty well but systems are really different. Systems are complex interactions of interdependent parts that give rise to emergent and often-unexpected (“non-deterministic”) behaviors. If you’ve ever kept an aquarium, you have a sense for the delicate equilibrium necessary to a healthy aquatic system. Add a new fish or trim too much of the macroalgae and you can suddenly veer into an ecosystem crash. Small changes can have large results, so you have to be very deliberate in how you manage the tank.
