<p>> wouldn't that violate free speech though?<p>Free speech can mean two things:<p>(1) The general philosophical postulate, that society is better when there is a high level of freedom in the exchange of ideas and critique of other's ideas.<p>(2) One aspect of the above is that government should not censor speech. Like the 1st amendment in USA.<p>But if most public discourse takes place on forums owned by companies, and the companies start to practice high levels of censorship, then we might formally satisfy (2) but still won't get the cultural benefits of (1).</p>

<p>> California's demand commonly goes from 18GW to 30GW in the same day.<p>That extreme intra-day variation is also partially caused by California's cheap solar power: Cheaper prices draw demand to those hours.<p>In other locations, (some) people (partially) adjust their consumption patters to follow the cheap wind energy hours, and this leads to different consumption patters. Less intra-day variation but but inter-day variation.<p>If California's prices were wind-dominated (typically a little more wind at nightime), or nuclear or burning dominated (stable), it would not cause such large variation in the intra-day consumption pattern.<p>This electricity price figure is readable, but 10 years old, so today the variation in California must be larger than it shows:<p><a href="https://www.eia.gov/todayinenergy/detail.php?id=32172" rel="nofollow">https://www.eia.gov/todayinenergy/detail.php?id=32172</a></p>

<p>> California's Battery Array Is as Powerful as 12 Nuclear Power Plants<p>From this graph we see that in the evening when solar power goes out, for next 3 hours (7 pm to 10 pm) California's battery array is as powerful as 12 nuclear reactors. Then the batteries are drained empty, and the rest of the night California survives by importing electricity from other states. And partially by running hydro power only during the nights, keeping it at zero during the day.<p><a href="https://www.gridstatus.io/live/caiso?date=2026-05-15" rel="nofollow">https://www.gridstatus.io/live/caiso?date=2026-05-15</a></p>

<p>Took me a while understand. So, the same person has both submitted their research article to the conference, and also acted as a reviewer for articles submitted by other people.<p>And if they in their review work have agreed to a "no LLM use" policy, but got exposed using LLMs anyway, then their submitted research article is desk rejected. Theoretically, someone could have submitted a stellar research article, but because they didn't follow agreed policy when reviewing other people's work, then also their research contribution is not welcome.<p>(At first I understood that innocent author's articles would have been rejected just because they happened to go to a bad reviewer. But this is not the case.)</p>
