I wouldn't have downvoted you for it, but it sounds like you missed this from the article:

While more modern rice cookers may use curie point magnetic switches, that's not what the original rice cooker used.

The user did not "miss this". They've reacted to it by saying that they have thought rice cookers work differently. Which indeed many of them do.

They replied to a comment about the bimetalic switch in this cooker with "I thought the circuit that powers the cooking was …".

While both you and they are correct that more modern devices work that way, that's not how this one works.

It's possible that they didn't miss that fact, but their comment reads as being a direct response to the discussion of the control circuit of the first rice cooker.
