Production, sure. Operational costs, not so much zero. I don’t understand how people think video streaming on any scale can be supported without any income. I don’t think they’re recent pricehike is reasonable, but to think anyone deserves to be able to stream 4k video (albeit low bit rate) without any sort of compensation is beyond me.
I pay for Youtube Premium, because I get a legit way to bypass ads and the creators I watch gets payed more than if I watched ads, but I also use an adblocker pretty much everywhere because they are intrusive and annoying. However I’m not under any illusion that doing so does directly hurt the income of the sites I visit.
Eh it’s still pretty hard.
If we check the numbers of English words from https://www.merriam-webster.com/help/faq-how-many-english-words and take a conservative estimate of 400 000 at the bottom of the page.
That means with the exact format of (word)(number)- 4 times has (without repeating words) 400000*9*399999*9*399998*9*399997*9 = 167957820891293697014400000 combinations. https://www.wolframalpha.com/input?i=400000*9*399998*9*399997*9*399996*9
The fastest super computer at the moment apparently sits at 1.1 quintillion Hz. Or 1.1 billion billion.
If that computer could make 1 guess every clock cycle it would still take it over 4 years (167957820891293697014400000 / 1.1quintillion = ~52 months ) to run through all possibilities.
Now that is a very fast computer, and we haven’t included the possibility of various numbers of words, different delimiter, or where and how often numbers appear. So unless you’ve really pissed off the US gov I don’t think you have to worry about it.
There’s a reason passphrases are the currently recommended way to generate secure passwords that are hard to guess but easy to memorize/type in.
