SETI@home achieved 50 times the computing power of the world's largest supercomputer [0], so it might actually be the only way to train the future GPT4 or GPT5.
GPT-3 will take way less time to make a good substitute that costs the power of compute than other historical time saving technologies. Unlike other historic technologies, they pretty much spell out exactly how to do it, and own no patents related to its creation. I have trouble seeing the downside.
Seems like you came up with the perfect word to describe your view on this. :P
I defintiely do think there is reason to worry about the future you're imagining happening, but as someone who has read through the papers on gpt, this is in no way going to end up being an exclusive proprietary API, so it'll very soon have open source and likely free or at compute cost options.
And well, if it doesn't make us better, no one will use it. If it does, you'll have to adjust to remain competitive, just like millions of professionals for going back millenia who encounter new technology in their chose and vocation. Ultimately, if it makes us better, and doesn't enslave us to the whims of a monopolistic holder (which the point of my post was to conjecture that it likely wouldn't) then it'll probably (though not defintiely) be better for us long term.
Hopefully it doesn't erode programmers abilities like spell check seems to have eroded people's spelling abilities but I fear that's a likely side effect.
This may be the first time that a proprietary coding tool offers such a great value preposition that I am actually interested in trying it out and potentially even paying for it. It's also a bit concerning that this will probably be extremely hard, if not impossible, to create an FOSS version of this technology, just because of the immense amount of computing power, and by extension money, needed to create GPT3.
I'm not that comfortable with the idea of a future where proprietary AI-based solutions and libraries (e.g. automatic testing libraries, which have been mentioned here a few times) are so powerful that I'll be forced to use them if I don't want to waste my time.
