First of all, there's no way anything can be cracked "instantly" if, from the context of the rest of the chart meaning "less than one second." Even if your password is five numbers, it's going to take quite a few tries to get it right, even if you used something obvious like a sequence in order, unless it was '12345'.
And that's my main gripe here: it's based solely on number and type of characters, when it's the content that's important. Frankly, if you do something like combine your two kid's names, if the person trying to hack you knows them, it's going to be a lot easier to crack 'JohnMary' than it would be nonsense text like 'bKPhwTcD'. The date you got married (say, 'June17,1987') is probably going to be quite easy for a hacker who can find out that much about you, even if, according to the chart, it should take 400 years. The big problem is that, no matter how many characters of which type you use, it's a trade-off between coming up with something the proverbial hacker wouldn't think of, while still being something you remember and so don't have to write down (which creates its own security issues). Probably the best solution for coming up with hard-to-guess but easy-to-use passwords is to use a password manager app, but that assumes you can find one that will stay in business without getting hacked itself, and that you can still can create a "master password" for the app that you can easily remember but no one else will be able to guess...which puts you right back at square one.
Don't think it can't happen just because it hasn't happened yet.
