<p>They are likely 200USD+ per TB, so one 250TB drive would be ~50,000USD.<p>There’s probably bulk pricing, but if you bought 40 drives separately thats 2,000,000USD in storage alone.</p>

<p>From what I understand, the laptop will reduce the refresh rate (of the entire display) to as low as 1Hz if what is being displayed effectively “allows” it.<p>For example:<p>- reading an article with intermittent scrolling<p>- typing with periodic breaks</p>

<p>Your claim doesn’t seem as definitive as you present it, for China and US at least.<p>Comparing China and the US it seems like theres a 150 billion ton difference in the cumulative emissions.<p>Most recent data shows China emitting ~8 billion tons more than the US annually. At that rate that’s about ~20yrs until they flip.<p>China’s emissions appear to increasing exponentially YoY whereas the US has seen reductions in recent years. That makes it seem like they’d flip in less than 20 years.<p>Obviously, the emissions on a per capita basis are still nowhere close.<p>From: <a href="https://ourworldindata.org/co2-emissions" rel="nofollow">https://ourworldindata.org/co2-emissions</a></p>

<p>That probably means you are an outlier.<p>One thing I see, is that people in urban environments typically opt-in to exercise (like voluntarily going on a run). Whereas those in more rural areas have more physical demanding jobs and responsibilities.<p>I’m an urban-based desk jockey who exercises a lot but it doesn’t really compare to my more rurally-based friends who are on their feet working blue collar jobs 5 days a week.</p>

<p>This makes sense. A lot of end-users have internet speeds that can outpace the decompression speeds of heavily compressed files. Seems like there would be an irrational psychological aspect to it as well.<p>Unfortunately for the hoster, they either have to eat the cost of the added bandwidth from a larger file or have people complain about slow decompression.</p>

<p>Yes, but if the phone shipped with less bloatware on the system partition, then maybe that partition would be made smaller initially.<p>Meaning the user would have access to more of the phone’s advertised storage.</p>

<p>What’s with the hate for proof-of-stake? Seems like the hate is directed towards the fact that those have more to stake, benefit more.<p>Can’t the same argument be made about proof-of-work? Those who have the ability to buy more compute, also benefit more.<p>Instead of buying GPUs/ASICs for mining you’re buying into the network you’re trying to secure.</p>

<p>The comment reads as ragebait or sarcasm but I actually can’t tell.<p>I don’t want to take away from Game developers but as a “corporate developer” I can attest that a lot of what you said about us is blatantly false.<p>I’ve spent a lot of time optimizing the performance of many backend services. This is a very standard practice. Having highly performant code can save companies a ton of money on compute.<p>In fact I’ve worked on a stateless web server who’s architecture was completely designed around a custom chunked/streaming protocol specifically to minimize latency. All changes to the service went through rigorous performance testing and wouldn’t be released if it failed certain latency and throughout thresholds.</p>
