On the other hand, within 120 years (and sometimes decades earlier), every human so far also has reached reach a point where they can't do anything anymore, reliably or otherwise. I don't think humans provide much of a precedent of sustained growth in reliable over anything other than a fixed period, and it's not clear to me that we have any idea whether or not we'll reach a ceiling in how reliable we can make LLMs before they outperform humans in tasks like programming.
