As to why that is dangerous, there are many reasons.
1. It devalues human life for those in power. Technology has strictly increased wealth inequality over the last century and this takes it to the nth degree. 2. Even in its current form, it is having society destabilizing effects, go on reddit and see posts from high school students asking what they should even study when its clear ChatGPT will be able to do (research, programming, math) better than a degree will prepare them to. 3. Google the paperclip problem. 4. The amount of computing resources it takes to run ChatGPT is shockingly / absurdly low, we are far far from the hardware scaling limits of AI so it is obvious that it will continue to improve, even without further algorithmic breakthroughs.
