<p>My father encouraged me to avoid elevators and escalators to the extent possible. He worked in a high rise and used the stairs for the first 6 floors of the building. People would see him come out of the stair well on the sixth floor to catch the elevator the rest of the way. Some coworkers eventually picked up this habit. He's 87 and is one of the healthiest people I know.<p>It's not just elevators and LLMs, we should regularly question all our technology usage. I needed to solve a statistical problem recently and it is easy to brute force an approximation by running a few million iterations on a computer. But I forced myself to attempt a theoretical solution first. It only took a few minutes to rejuvenate concepts and "foundational cognitive ability" that would otherwise be fading.</p>

<p>I looked through your comment history to ensure you haven't already answered this. But what made you get tested ? Did you have risk factors ? No problem if you'd rather not share.<p>Related, I was told by a doctor to get screened after turning 50. But a reasonable self-estimate given all my risk factors puts my chances of having colon cancer at 1 in 10000. A colonoscopy has a false positive of ~2%[0] for my demographic. Meaning if I get a positive result, it's actually ~200 times more likely that I don't have cancer. It's hard to justify a screening given those odds and the 99%+ chance I will waste my time treating and worrying about a disease I don't have. My guess is an insurance company wouldn't cover a colonoscopy for those reasons.<p>[0]<a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7147410/" rel="nofollow">https://pmc.ncbi.nlm.nih.gov/articles/PMC7147410/</a></p>

<p>Returns are already a major expense for wholesalers and retailers. Hopefully accounts using chatbot agents will have to pay a restocking fee on returned items that is partly paid to the wholesaler.<p>Perhaps this post is merely for publicity's sake much like retailer's cryptocurrency support claims in 2018.</p>

<p>The correct term is "chatbot" in most cases. I've witnessed people make dumb decisions somewhat blindly because "AI" recommended it. If they had called it a chatbot maybe some skepticism would have kicked in.</p>

<p>Fun site and your Muse is a near match to Meta's.<p>Curious, did you come up with the name "Muse" and make the character art ? Or did you and Zuck coincidentally use similar LLM prompts. If Meta's version was AI gen'd they wouldn't be able to copyright it suggesting it's likely human designed. But if that human design is a derivative of your art, which it seems to be, then they wouldn't have copyright either.</p>

<p>From personal observation, many Christians  see oil as a unlimited natural gift from God and view alternative energy sources with disdain. Not sure if that was a deliberate strategy on Big Oil's part but it effectively solidifies massive political support.<p>By similarity if Thiel can equate AI regulation or restricting government AI funding with the Antichrist he could guarantee political support for decades.<p>I don't recall Thiel ever lecturing about religion or the Antichrist prior to his involvement with government contracts. It's hard to believe any of this is sincere.</p>

<p>Agreed that initially referring to it as "brain tumor" would have been fine.<p>Thanks for sharing your story too, perhaps this condition isn't rare. Coincidentally I once went into bar and vaguely recognized a roommate I hadn't seen in years. His appearance had changed and he now had remarkable Hulk like features. I restrained myself from asking but I honestly thought he looked great.<p>We chatted and he shared that he had "brain surgery" 2 weeks(?) prior to remove a tumor on his pituitary gland. He just woke up one day and his vision was distorted. The next day he woke up blind which lead to him getting a diagnosis and surgery. The tumor had also caused pituitary disfunction which induced giantism.<p>If I recall, the surgery was performed going behind his nose through an incision in his mouth above the posterior of his upper lip which differs slightly from the approach in the OP. It's amazingly fortunate that this is an option given it looks inoperable from the MRI.<p>I'll also share that towards the end of our conversation he thanked me for not commenting on his appearance and that he was self-conscious. It's compelling, especially when someone looks good, to mention it, but there's no need to lead with it.</p>

<p>Regarding a comment the author made in passing:<p><i>For the increasing number of people who have cataract surgery, the eye’s lenses have ben replaced with plastic, which usually have a fixed focus. (Artificial lenses that can be focused are under development.)</i><p>My dad recently had cataract surgery and I just assumed he was getting would be a deformable lens that would give him the ability to focus again. Does anyone know why it is so hard to develop such a lens ? As far as medical breakthroughs it seems like low hanging fruit and most people over the age of 45 could benefit from such a surgery since that is the age at which our lenses begin to harden and can no longer be shaped by our ciliary muscles.</p>

<p>In addition to those consultants, Cynthia Stine of egrowthpartners.com was recently interviewed in The Week's Jan 25, 2019 "The Last Word" column and her firm helps Amazon Sellers with Marketplace challenges.<p>Also, Amazon's Selling Partner Summit is taking place next week at Amazon HQ. It is currently sold out but maybe there is a waiting list ? I'll be attending primarily to make internal contacts should I ever encounter a problem with my account but I can't say for certain if that conference will be helpful in that regard.

<p>This article implies that if you can't change your diet then you could achieve similar results with chewing exercises. The comments below mention <i>mewing</i>, but I suspect greater force would be better. Googling "chew toys for adults" gave interesting results but they are mainly used for anxiety and ADHD. Curious if anyone knows of a chew appliance for children or adults that would address the issues mentioned in the article.</p>

<p>A bit of a tangent, but does anyone know if a "paper PhD" is still and option ?
