You also use an OS and browser which is space age technology compared to what they had in 2005. Back then a kid could write an email to install a rootkit on your computer. Now you'd get paid $100k+ if you could work out how to do that.

It also used to be common knowledge that if someone has physical access to your device, its game over. Which is something that is becoming rapidly untrue. If I hand my macbook to my friend for a day, I can be quite confident they haven't been able to defeat the boot chain security to replace my kernel with a malware version like you trivially could pre secure boot environments.

Another piece of common advice was to not use public wifi because anyone could steal your password or credit card details. Security advice from 2005 really hasn't held up much at all.
