One company having that much power is a different matter, and I address it by looking at how we can distribute GPT training through decentralized and open platforms.
It won't be me or you. Whoever it is, they will not share any of the economic upsides of AI with the public unless they are legally forced -- zero, zip, zilch, nada. Even then, they will keep the lion's share for themselves, and they will use their surplus to shape society to their advantage.
So yes, many millions of us have a big problem to worry about, especially considering how much struggling there already is now.
But even if it stays in private hands, one company monopolizing a technology and keeping it expensive/out-of-reach is generally not how technological innovation works. There is generally intense competition between providers, with each aggressively cutting prices to capture market share.
Pure theology
We're already witnessing this with the creation of textual and graphical content through ChatGPT. It's now possible to generate various types of text content and a wide range of graphics at the cost of 10 cents for the dozen ChatGPT API calls. And the work is completed in a few minutes, as opposed to several hours. This represents a several orders of magnitude increase in per capita productivity for these specific tasks. As AI technology advances, the scope of applications benefiting from such productivity boosts is expected to widen, which means human civilization will experience a revolutionary increase in productivity, and with it, resource abundance.
Often with text, the GPT is more of an assistant/advisor/proofreader for me, rather than a stand-alone creator of quality content.
Sometimes it works really well for emails. Like for producing responses to formal communications. It can save cut the time to respond from 10 minutes to 30 seconds.
I for one, would be overwhelmed. In the meantime I will be passionate and joyful about the things I like regardless of whether AI can do them a million times better. I have fun doing it.. while the AI is.. just AI.
