I have a unique situation since I can't hear well, and everyone being on WFH has been a huge benefit for me: since everyone's got their own microphone/camera/etc, they come through clearly enough that my captioning app can actually understand them well - typically I get captioning as live CART through a crap conference room phone. Being able to hook my captioning app on my phone up to my laptop's audio out and jump on a Teams call with just a few minutes' notice has also been a huge benefit in easily being able to collaborate with my team and talk through problems.
I'd worked from home before, but never in this kind of remote-first/remote-only scenario, and now that I've gotten a taste of it I kind of never want to go back. I understand that other people are more extroverted than I am, and can hear normally, and it's not an ideal situation for them - but it's been pretty awesome for me.
