All indications are that we are going to experience a not-so-great depression. Not a recession, an honest-to-goodness depression. 2020 will be down YoY in terms economic output probably across the world, and it wouldn't surprise me if that's not only true for Q2-Q4, but if it also lingers into Q1. My guess is that we will feel like things are growing again this time next year.
Some economists are hoping for a better outcome than this of course, but you can connect the dots and see what people are planning for, as you've done here. Airbnb is not alone in planning for depression, and the travel industry will be worse than most.
