But that's only temporary.
It's like developers starting over and promising themselves that they won't accrue technical debt this time. And then life happens and you need to push that feature quickly and a few years down the line, you're sitting there saying "we need to start over, this is too much trash held together by hopes and dreams".
Companies will cut corners, because that's their main focus. Politicians will reduce regulations, because that's how they stimulate locale economy, and we're back at square one in no time.
The only lasting shift, aside from potentially more work from home, is people making sure they'll always have an extra package of toilet paper. They won't flee the cities (where viruses can spread much better), even though the rent is killing them, and they won't go into voluntary lock down the next time a thousand people die in China of some lung disease.
Similar to what happened after the financial crisis with additional financial regulation.
I have no doubt another pandemic will happen, and we'll likely have forgotten what it's like, so having policies in place becomes even more important.
