'Everything is moving too fast': We test out the new GPT-4, and it's astounding

I've written about technology for 25 years and I have never encountered anything as fascinating as ChatGPT. Seeing its responses often gives me a sense of vertigo, like everything is moving too fast. And everything has just got a little bit faster. Last night, OpenAI announced and launched the latest version of the model which underlies ChatGPT, GPT-4. The new version brings several advanced capabilities, including the power to ace legal exams, understand images and digest prompts up to 25,000 words long.
