Congratulations, you’ve just invented digital images.

Dictionary attacks are definitely not a magic bullet, they require a lot of processing power, just like any other brute-force attack, but not more because of their longer length, as has been implied.

True, there are a lot of english words, but the amount of common words is relatively small. Most people aren’t going to choose a password like “MachicolationRemonstranceCircumambulationSchadenfreude”, even if it were generated for them (which is unlikely).

Sure, it is comparable to a standard 8 characters passward, but even that kind of password is verging on the insecure (it is the absolute minimum, which should be avoided when possible).

There are also a lot of symbols when you count emojies and the entire Unicode standard.

You can’t compare a 46 random character password to a password composed out of words, the entropy of each is very different. Your kind of password is vulnerable to dictionary attacks which are way more common and easy than brute forcing every possibility. A 50+ characters unique random password for each service that is stored in a password manager which is encrypted with a 20+ characters random password is the most secure and future proof (for now).
