Your link goes to something unrelated. Course, it's twitter, and their links are very weird, so you could have linked to something relevant, but twitter's showing something else.

Here's a direct quote from the AMA Gates did on Reddit:

The question of which businesses should keep going is tricky. Certainly food supply and the health system. We still need water, electricity and the internet. Supply chains for critical things need to be maintained. Countries are still figuring out what to keep running.
Eventually we will have some digital certificates to show who has recovered or been tested recently or when we have a vaccine who has received it.
