A friend startup-pitched exactly this idea (remote monitoring by request, e.g. late-night walks home) to me 6 years ago and found me less enthusiastic than he had perhaps hoped, it's strange to think about how many people might converge on similar ideas at the roughly same time

Not particularly surprised to see it realized in this way

I have a few surveillance ideas more interesting than that but think they are immoral.

It’s sad that someone else will implement them anyway.
