When you are walking around in the "outside" world, you can expect there to be no privacy at all. Everything you see, and everyone who can see you, just think there are cameras everywhere, everyone has a cell phone, and every building has CCTV. Once you are aware of that, you just do your best to blend in like everyone else, like the millions of other people who don't seem to care. If you wear a cap or hat, shades maybe, and a mask to cover your mouth, then automated systems will have a very difficult time to consistently identify you.

Many places have stopped requiring people to wear masks, but a lot of them still do. I have one just because it's become a habit for me, and I'll keep wearing it for a few months or years into the future while it still looks normal. Most indoor settings still "suggest" you have a mask anyway.
