<p>>Apple tried the damnedest at that during their intel era.<p>The story I heard was intel failed to deliver on die shrinks that were supposed to increase thermal efficiency.  The fan also had poor routing and basically did nothing.<p>Apple was clearly  not  at the top of their game for that design, nor would you expect them to be as the decision was likely already made to move to apple silicon.</p>

<p>>Surely if the machine you go to for answers regularly makes things up you would just stop using it?<p>Not necessarily, namely because P != NP. Verifying the correctness of a solution is faster than solving it.  Thus a system that outputs 99% incorrect solutions and 1% correct solutions can still be <i>incredibly</i> useful.</p>

<p>Thermal dissipation scales quartically with T, that's about as graceful as you can get from a physics POV, very few things scale at that rate.<p>COTs GPUs throttle at about 90-100C but that's because they have plastic parts and solder that melts.  Those are relatively easy to eliminate.<p>We haven't tried much to scale up operating temp.</p>

<p>Pinch to zoom on an early iphone navigating those fixed-width sites worked surprisingly well.<p>I still prefer it to the responsive pages where stuff moves unpredictably and annoyingly.

<p>Right but that's because you've now layered in government control.  401k plans are more heavily regulated, often negotiated by the employer rather than the employee.<p>The real question is why are employers able to limit employee 401k investment choices and employee health insurance.  This is not freedom.</p>

<p>>DOGE found an actually highly efficient Federal government<p>For anyone that has worked on either side of government procurement it is obvious that this is not true.<p>It's quite common for contracts to no longer make sense yet neither side wants to cancel them due to the paperwork involved.

<p>Yes it  would be better if it took these into account but doing so would not change the overall numbers.<p>Risk of perforation is something like .03% and almost never fatal whereas a colonoscopy reduces colorectal cancer mortality by 60-70%.<p>>And you have to consider the opportunity costs of consuming the doctor's time, the labwork, and the facilities, possibly delaying treatment for someone else who actually needs it.<p>That is also rarely true.  More often, greater demand for a service soon yields economies of scale, more efficiencies and overall more patients served at a lower price.  Low volume is expensive, high volume is cheap.</p>

<p>Not sure it's so clever because I completed it as "not always wrong but often wrong", which their graph in the article seems to confirm.<p>Mainstream predictions are easy, usually it means predicting status-quo.  It's the out-of-consensus that matters (right 2 quadrants) and it  looks like they are slightly worse than 50/50 on those.<p>Props for publishing it though.</p>

<p>I doubt that, there really wasn't much effort put to allowing GPUs to run hotter.  You can always add a heat pump to create the thermal gradient of the GPU can't handle it itself.</p>

<p>>Certainly, you should attribute a significant proportion to the people who installed the automated system and even more to those who designed it.<p>Indeed, but what happens if/when they choose to sell the system and someone else buys it?  Now the owner is who is generating the value.  Even if he hires some maintenance worker to come by once and awhile and check up on it, it is the system (aka the capital), not the worker that is generating the vast majority of the value.</p>

<p>That is true but likely only temporarily.  Why is the single worker even needed?<p>We tend to have a pretty human-centric worldview so if there's a single human working to keep a hotel running, our default is to attribute all the generated value to them when it really isn't the case.  You can imagine that hotel at some point in the near future goes from requiring 1 worker to keep it running to zero.</p>
