  NEON has nothing like it; on x64, the closest thing is the SSE4.2 string-comparison instructions (pcmpistrm), which are slow.

  Building superintelligence may be the most important thing that has ever happened in business, and it will still be dwarfed by some startup that has not been founded yet.

  it is both true that you know maybe creating super intelligence will be the most important thing yet to happen in the history of business or human society and also that it will pale in comparison to some new startup something that hopefully one of you will do.

  Opus is the silly but funny coworker you keep around; Codex is the weirdo in the corner who reliably gets things done, and no model wins on every axis.

  Some other comparison is like, Opus is like the coworker that is a little silly sometimes, but it's really funny and you keep him around. And Codex is like the, the weirdo in the corner that you don't wanna talk to, but is reliable and gets shit done.

  Their words

  people don't decide like that at the very least you'll have to show them three or four or five skiing holidays from which they choose because we can't really choose in the absence of comparison.

  The United Kingdom is the one rich industrial country that cannot run on solar alone, and it has to build wind at scale instead.

  solarenergy

  Their words

  The only highly populated industrial country unable to trivially meet its electricity and synthetic fuel needs with solar alone is the United Kingdom, due primarily to a high population density and high latitude. The Nordic and Baltic countries are tiny by comparison. Among other problems, the UK needs to decide if it wants the future where energy is cheap and it is rich, or the future where energy is expensive and it is poor. If the former, it is time to get serious about large scale deployment of wind power, using home-grown vertically integrated technology at prices as low as $10/MWh.

  The Renaissance and early modern period were not a better time to be alive than the Middle Ages they are said to have rescued Europe from.

  Europe

  Their words

  I am not here to tell you that the medieval period is a specifically peaceful time, but it pales in comparison to what goes down in the early modern period, in which both the apparently beloved Renaissance and Enlightenment periods lie.

  At current ride volumes it would take a leading robotaxi fleet about twenty years without a single fatality to show it is as safe as the average human driver.

  Their words

  At current deployment rates it will take Waymo about 20 years with ZERO fatalities to show they are net as safe as average human driver fatality rates (including the old cars, impaired drivers, etc. in that comparison baseline).

Professor at Carnegie Mellon working on self-driving-car safety; writes Safe Autonomy on how autonomous vehicles are and are not shown to be safe.

• Our readingkorrents.com

  A carmaker's claim to be the safest is mostly an artefact of comparing a new car against a fleet average twelve years old.

  Their words

  Any true safety improvement for Tesla is good to have, but is much more likely due to comparison against an "average" vehicle (12 years old in the US) which is much less safe than any recent high-end vehicle regardless of manufacturer, and probably not driven on roads as safe on average as where Teslas are more popular.
