<p>That’s just playing semantics. Nobody is talking about, “objective facts” or need define them here. If the step time is measured in days, and your model takes years to train, then it will never get trained to completion on consumer hardware (the entire point).</p>

<p>Ah yeah, well I didn’t know it was that high!<p>But I’m responding to the rescue mission comment, which, since Vietnam, have overwhelmingly employed helicopters (Huey’s then, Black Hawks today). But machinery aside, the larger point is that air operations will likely go worse here than they did in Vietnam, unfortunately for both sides.</p>

<p>I see this critique about autoresearch online often, but I think it’s misplaced.<p>Here’s a use case that may illuminate the difference, from my own work at Nvidia. Im currently training some large sparse autoencoders, and there are issues with dead latents. Several solutions exit to help here, such as auxk, which I can certainly include and tune the relevant params as you describe. However, I have several other ideas that are much different, each of which requires editing core code (full evaluation changes, initialization strategies, architecture changes, etc.), including changes to parallelism strategies in the multi-rank environment I’m using. Moreover, based on my ideas and other existing literature, Claude can try a number of new ideas, each potentially involving more code changes.<p>This automated run-and-discover process is far beyond what’s possible with hyperparam search.</p>

<p>I agree with the sentiment that there are use cases for web scraping where an agent is preferable to a cron job, but I think your particular example can certainly be achieved with a cron job and a basic parser script. Just have Claude write it.</p>

<p>I understand your argument but it just seems like you’re purposely being contrarian.<p>Here’s why what you wrote seems needlessly contrarian: Amazon just posted an $18B quarter, so there is no pressing financial pressure. Okay, so you suggest this may be a last resort in lieu of retraining, but we’re talking about 14k jobs across many teams (I know of at least 40 affected), levels, and job families. The idea of needing to cross train is obviously not the culprit at that scale;  An SDE laid off from one team can easily perform the same tasks on many others internally. This also completely ignores how Amazon works internally, with managers required to rank employees for pip, and, for events just like this one, URA, regardless of whether or not they deem them to be competent or not.<p>Of course, Amazon has also been documented to use automated processes for pip/layoffs, and the idea that layoffs involved any ounce of consideration as a last resort is so unbelievable it feels almost inflammatory.<p>The notion that criticizing one of history’s most profitable companies laying off thousands (at the height of their profits) is the same thing as stating, “every company beyond profit X should never do layoffs” is a blatant misrepresentation and ignores any context.</p>
