@regehr I'm reading, reading, waiting for something new, and the new “idea” is the implication that using an LLM makes using C safe. Or safer. I'm not sure. In any case it's irresponsible to not use one, so using one is good, or less bad, surely.

Man,

  • wrong tool for the job
  • still the wrong language to be using in 2026 for 98% of what it is used for, even with an LLM
  • are you writing software piloting any bridges that I can avoid standing on?

@void_friend @regehr Ugh, a list of things we all already know about C, which is fine because it's a neat list, but then "LLMs are better than us at this". Delete tab.

@jripley @void_friend yes it's very 2026 to write a 2012 post with 10% of LLMs at the end

@regehr @jripley @void_friend It's not undefined behavior—it's strategic optionality for maximizing performance.
