That's already the case. GPT-3 might be faster, but there's literally millions of humans producing absolute garbage for pennies. I'm talking 1000 word, quite readable articles (that make little sense if you pay close attention) for $5 or less.
Used to be a time when it was really easy to rank at the top with just that kind of content.
But Google managed to filter all that out, for the most part. Pretty sure they can deal with computer generated text, too.
Hyperlinks still play an important role - if someone links to the article's URL, that automatically increases its rank. No one links to trash. Links from known spam websites will downrank the article or the whole website really fast.
Timestamps used to be abused back when Google preferred the newest stuff - just update it every day or hour and it's the freshest article in the world in Googlebot's eyes.
It's a really impressive piece of technology, and they have a ton of experience fighting abuse on their SERPs - it's happening constantly and it will continue to as long as search engines exist.
I mean, for a while Facebook may get paid for presenting ads to GPT-3 spam bots, but eventually advertisers will catch on that the people are gone.
Maybe we can unleash bots that appear exactly as humans, ruining the advertiser gravy train forever.
If our weapons (programs, scripts, "AI") become half as effective as theirs (the advertising giants'), they'll drop nine-plus figures paying to have ours outlawed, guaranteed. The only thing that might save us from that in the US is that national ID of any sort is pretty unpopular across party lines, and that's effectively what it'd be.
I wouldn't be surprised if they're already quietly laying the groundwork for such an effort.
In the US it's not possible to catch a flight across the country or obtain a loan without providing your SSN. And the SSN was originally, extra-explicitly, not allowed to be used for anything but administering social security benefits.
Despite what might be described as an absolutely huge market signal that there's desire and need for this, resistance to actual national ID is so high among elected officials that propositions for it have, so far, always been DOA. Maybe national IDs really are terrible and it's worth the shared-over-the-population pain and expense not having one causes in a modern society and economy, IDK.
I'd guess it's one of those things where network effects make it hard to get off the ground, and given the nature of it, especially hard to get off the ground without government buy-in from the beginning, as so many of the ways it'd be useful for saving time and money and reducing risk are tied to interaction with the government. If a market-based solution for it were desirable, for whatever reason, defining some clear and interoperable standard at the government level would probably be necessary to make the market viable, no matter how much latent demand there may be.
Further, imagining the user experience of a non-heavily-regulated/standardized ID market, it seems like it'd necessarily be so hellishly bad it'd never gain adoption. Having 5 different IDs and sometimes having to get new ones or drop an old one seems no better than using credit cards and our social security numbers as IDs, like we do now. It seems to me the epitome of something that can't possibly be any good as a market solution, unless it's so monopolized or regulated that it's indistinguishable from a government solution, except somewhat less straightforward.
The idea that "You won't believe what <popular/unpopular> celebrity said!" or "Trump outrage #942134!" gets tons of engagement when written by a human, but will make people leave if it's generated by an algorithm is hard for me to square with the social media landscape that actually exists.
If ad impressions & clicks don't drop, Google, FB, and others won't give a shit where the content's coming from. If impressions & clicks go up (not an unlikely outcome, I'd say) they'll even encourage it.
If the SERPs are filled with garbage, their search algorithm loses competitive edge. We may need to go back to a reputation graph-based system. That sort of thing doesn't scale, and Google isn't doing this at all.
In fact, all of the platforms may suffer. How will Facebook keep out GPT-3 spam?
