I mean, you *can* read arbitrary memory very easily with a small amount of JavaScript on your website, from the visitor's machine if the visitor does not have sufficient security; for example, the Spectre/Meltdown bug and others. Mitigations exist for many of these.

Then again most people don't lug 2 and sometimes even 3 computers around with them on a bicycle like I do.
