> In general the security model of desktop operating systems is woefully inadequate for the modern era. Given the sheer volume of software known to do things not in the user’s best interest it’s borderline insanity that we hand it the keys to the kingdom without so much as a second thought with such frequency.

This. It must be the problem of having grown up with it that makes people not realize it.

Software will need to operate like people in the real world. You can give your friend power of attorney, but usually you don't, you find a better way to get things done.

Exactly. It’s not so different from how popular desktop operating systems used to be single-user, which turned out to be a security nightmare, and so shifted to a multi-user design. It’s time for the next evolution.
