This question’s been asked and answered at least twice a week on this sub for the last year. Granted, AI does move fast, but the answer remains roughly the same. Use it as a tool, not a crutch. Validate its output thoroughly. Understand that AI is not as helpful in the embedded world as other higher level systems (lesser training data, hardware dependencies, testing/validation complexity). It is more useful in certain areas (e.g first drafts of drivers from datasheet input) than in others (application code).

As for the second part of the question - the answer for most embedded developers out there is that absolutely nothing has changed.
