How to get back into AI in 2025?

Question

I feel completely left behind. Last time I was up to date, it was FastText and fine-tuning the last layer of a neural network. Now it's BERT, LLMs, DeepSeek, Gemini Flash, RAG, LoRA, vLLM, LangChain, agents, and whatever else I'm missing.Where do I start to get back in? What&rsquo;s the best way to update my knowledge without drowning in hype?

I want to know how you got out of the AI hype. I try to ignore it but it infects everything.
