Altman’s point is that the falling cost of using AI is another indicator that artificial general intelligence (AGI) is “coming into view”. AGI is an artificial intelligence that is on a par with, or smarter than, human intelligence, and developing it is the whole reason that companies like OpenAI exist because the benefits of AGI could be truly world-changing, despite the dangers that we keep getting warned about. It’s worth reading the whole of Sam Altman's blog post because it very much reads like a warning that the future is coming sooner than we think and that we really start to need to prepare for how the world is going to change.
