# What do you think about AI? > Source: > Published: 2026-09-19 16:15:54+00:00 AI is an incredible tool, but it’s important to remember what’s actually happening under the hood: **Frozen Weights:** Once an LLM finishes training, its weights are strictly read-only. The model doesn’t learn, adapt, or rewrite its own code while chatting with you. **No Active Inner Life:** There’s no mind running in the background when you close the tab. It only “thinks” during the exact split second it takes to run a forward mathematical pass and predict the next token in response to your prompt. **Context Limits:** Because memory is bound by a strict context window and parameters are static, current models can’t naturally evolve or build true continuous understanding. They are powerful pattern-matching tools, not self-updating intelligences!
