No it's not the same as your grandma. The point is that it's now more expensive to find the correct information to learn from. You don't know it's an LLM ahead of time, and you may spend hours until you figure out something is off. Hence why reputable sources will become more valuable.

Did you read example #1? I'm not talking about some piece of code from an LLM that you can verify or some political opinion that you can take with a grain of salt, but information that you can only gain and/or judge through expertise:

If you're not a physicist yourself, you can't judge "information by its merit" on specific physics topics, because you don't have a solid baseline.

Similarly, in growing plants, each plant has its own peculiarities, and only people experienced in growing it can tell you anything useful - it's knowledge accumulated by trial and error. Not knowledge that your "great discerning mind" can assess on its own. Even a botanist can't tell you the ideal growing conditions of a plant that they've never studied before.
