Never said that it's a good thing that LLMs know less. It's a negative thing and I suspect it's like that because of good documentation in PDF format. So you usually need a lot less help in forums, and the doc itself is less discoverable.
The Pico has 2MB to 16MB on board flash with XIP in all the configurations AFAIK.
Fantastic documentation, even if in PDF form, which makes a bit less accessible for us and especially for LLMs training data crawlers. In general LLMs know a great deal more about ESP stuff than the RP2040.
came across to me, as if the entire item was a reason why you prefer the RP2040-based systems.
And I meant that the microcontroller itself (the RP2040 chip) lacks built-in flash. I realize it's on the boards instead, that is the thing I personally don't like since you can never have a single-chip solution.
I would add "no on-board flash" as a big negative, at least to me it makes it less of a "true" microcontroller.
