A few years ago, if you visit a site, your laptop grinds to a halt and the fan starts spinning like crazy, you know there is crypto mining happening on the site.

(btw that was a really good showcase for WebAssembly. Too bad it's used for illegitimate purposes)

Pretty much all sites do that to my laptop these days if I don't enable uBlock Origin.

Google Meet consumes 25% of each of 16 hypercores, ffs. On a 7840u. Laptop becomes a toaster.
