1. How would the Covid response have been/be different if there were no social media?
I'll cop to a bias right up front here, but I think it would have been far better. I think that the information would have transmitted more slowly, but more accurately, and the accuracy would have largely cancelled out the slow. I think the level of divisiveness would have been FAR less, and there would be a lot less "statements" being made through the compliance with the guidance. I firmly believe that the social media does a lot to sort of "set" the expectation of how people should react. Social media is all about conflict, and escalation, and "owning", and I think that aspect of the response would have been greatly suppressed. (If you disagree, that's fine, but for one moment consider the difference between responding anonymously over a social media platform versus face-to-face in person.)
2. How would the Covid response have been/be different if there had been no technology like Zoom, Uber Eats, Amazon. No online work meeting platforms, no delivery services, no grocery/liquor/weed store pick up.
The response would have been FAR, FAR less effective. We - humans (not "Republicans" or "Democrats) - have a tendency to get stale on things. We saw as the COVID response went on that people's willingness to sacrifice waned over time; that would only have been worse if these services weren't there to cushion our sacrifice AND cushion the impact to those businesses greatly affected by the virus. I'm thinking of all the more restaurants that would have gone out of business if they couldn't pivot to a take out model, and all the additional jobs that would have been lost had they closed.
3. How would the Covid response have been/be different if North America had been more aware/concerned about Covid-19 in December 2019?
I don't think it would have been materially different in scope, it just might have started sooner. That may have prevented some of the larger, early hotspots, such as those in Washington state and New York. It would have potentially brought us the vaccines that much sooner as well.
