Where should someone who wants to learn about Artificial intelligence start from?

The term "artificial intelligence" is a bit overloaded. Let's divide it into two categories: Large Language Models (LLMs) and ... everything else. If you're interested in ChatGPT and similar technologies, you need to understand how LLMs work in general and how to use them. If you're interested in what's happening behind the scenes, you can start experimenting with Neural Networks on your own. It's actually surprisingly easy now to train your own network on your own laptop. It's fun and will help you understand what AI actually is on a completely different level. I hope this helps.
