  • Ok, so it’d be like if a wikipedia page about jesus said he was “our lord and saviour” instead of saying “some people consider him to be their lord and saviour”. A page for “Lord and saviour” as a phrase might still list jesus as one possible link.

    Basically taking a first person position on it, instead of a third person position. Like grokipedia is writing from first person perspective that Hitler is the fuhrer, which when you consider that it is a significant departure from the wikipedia article, as only 0.01% of the content of grokipedia is, suggests it’s a hand crafted article written by someone that would refer to hitler personally as the leader, and not as someone some people used to call “the leader”.

    There is a reason it was edited immediately as soon as people noticed, due to how bad it looked once pointed out.



  • To be fair, the wikipedia article says he was called that by the people that followed him. It never calls him that itself.

    The grokipedia article, just calls him that.

    A subtle, but very important, distinction.

    Not to mention the other important part where grok buries any mention of the holocaust 13000 words in, where as it’s in the intro on wikipedia.

    Keep in mind, by default, grokipedia started with a copy of what wikipedia said, so any changes are what was hand-edited on purpose.

    The changes speak to what they wanted it to say and do differently.








  • So, a 55-inch TV, which is pretty much the smallest 4k TV you could get when they were new, has benefits over 1080p at a distance of 7.5 feet… how far away do people watch their TVs from? Am I weird?

    And at the size of computer monitors, for the distance they are from your face, they would always have full benefit on this chart. And even working into 8k a decent amount.

    And that’s only for people with typical vision, for people with above-average acuity, the benefits would start further away.

    But yeah, for VR for sure, since having an 8k screen there would directly determine how far away a 4k flat screen can be properly re-created. If your headset is only 4k, a 4k flat screen in VR is only worth it when it takes up most of your field of view. That’s how I have mine set up, but I would imagine most people would prefer it to be half the size or twice the distance away, or a combination.

    So 8k screens in VR will be very relevant for augmented reality, since performance costs there are pretty low anyway. And still convey benefits if you are running actual VR games at half the physical panel resolution due to performance demand being too high otherwise. You get some relatively free upscaling then. Won’t look as good as native 8k, but benefits a bit anyway.

    There is also fixed and dynamic foveated rendering to think about, with an 8k screen, even running only 10% of it at that resolution and 20% at 4k, 30% at 1080p, and the remaining 40% at 540p, even with the overhead of so many foveation steps, you’ll get a notable reduction in performance cost. Fixed foveated would likely need to lean higher towards bigger percentages of higher res, but has the performance advantage of not having to move around at all from frame to frame. Can benefit from more pre-planning and optimization.


  • Overall is that even a deal over a used headset? Even a fully featured non-stripped down one? Like given what features his headset does have, it’s comparable to some pretty old headsets… and it likely does even those bare minimum features more poorly than an older used headset would. Not to mention comfort.

    Like a 10 year old Rift CV1 has almost as much resolution at 90hz/fps instead of 60. And while it’s lenses would be relatively terrible now, they were pretty much the best option of their day, and likely still better than whatever this dude sourced. Not to mention their motion to photon was around 12 ms. The absolute best result this guy can hope for is 16.6ms, and that’s only if everything else in the pipeline is faster than the screens refresh rate… maybe it is… but I wouldn’t bet on it personally.

    I’m sure it was a fun project though.




  • Yeah, very much looking forward to headsets with 8k panels. Most are up to 4k now, and it’s getting pretty good. If it stays at 4k for a bit, that would be fine. But it’s definitely an area where 8k will still be a very noticeable upgrade.

    Even if the only short-term practical use for an 8k panel is how far away a 4k or 1080p screen would be clear to read in an augmented reality situation, that would be reason enough. But I personally will gladly lower quality settings to run VR games in 8k instead of 4k as well.


  • Probably something like this. Except not trained to be a rebellious troll. Part of her training set is his chat, hehe. Though despite this one being “evil” neuro, I think normal neurosama is more of a troll now, lol.

    This is clipped segments from a live stream, so it jumps ahead at times. It has links to the source channel if you would prefer a full video. This one is probably already too long for most people though.

    He does end up figuring out why she has so much trouble correctly inserting code in the right places later.

    Edit: also, everytime she says “filtered”, it means whatever she was gonna say would have broken youtube or twitch rules. He has two filters, one on the text generated and one on the text to speech. If the text one catches it, it just outputs filtered instead, if the speech one catches it, she’ll still type something terrible, but only say roughly the first syllable or 2 before the speech is cut off.
