<p>I'd suggest looking at the review itself, there's an X-the-everything-app thread on it.<p><a href="https://x.com/Gregorein/status/2038953944475472316" rel="nofollow">https://x.com/Gregorein/status/2038953944475472316</a><p>Note that Rails was built as a framework for making blogs, I'm having trouble understanding what 78,000 lines of ruby in the context of a Rails blog could ... do.<p>I'm sure there's some powerful ugly stuff in Office but in a good code that's calcified kind of way. It got that way over like 30 years of releasing to the public across platforms, not over a weekend.<p>I'd be surprised if microsoft.com is shipping their entire test suite unminified and their back-end posting rich text editor with index.html (with two title tags in the head) and rendering the entire DOM for desktop and mobile regardless of your platform.<p>I'm not critiquing Garry or the site. I think it's great people are using AI to build things that bring them joy, or that they find useful. I certainly do.<p>I am opposed to the idea that we've decided to go back to measuring work in terms of lines of code. It has always been the worst metric on earth as a proxy for productivity. Every line is a liability, and it always was. AI has not changed that, if anything it's amplifying it.<p>The best PRs remove code, not add, and the only companies that seem to have exponentially grown their revenues in line with AI-generated LOC are OpenAI and Anthropic. Everyone else seems to be rummaging around for an ROI.</p>

<p>Companies over-hired in 2021 assuming that their COVID metrics explosion would persist, but they didn't. We saw low attrition for years, and a low-hire/low-fire employment environment. Then the time came to pay the piper.<p>The tech everything's-hypergrowth era is, for now, over. Most of the low-hanging fruit that we've collected for the last 20 years of bull market (putting tech into every business) is gone, and companies hired in advance of having the next business to overlay on their current ones. For many that didn't materialize.</p>

<p>At least the top 4, unclear about the 5th, are strongly associated with obesity. That would make someone high-risk and testing potentially warranted in like 70% of the population. Asymptomatic <i>and</i> low-risk is what I said. The incidence of hypertension is so high in the general population it’s almost always statistically supported (even though basically every doctors office takes it wrong, even cardiologists, amazingly).<p>On the other end of the spectrum, what doesn’t make sense is testing a random person off the street for Ebola. The prevalence approaches zero and symptoms are fairly noticeable, so any positive test is definitely wrong.<p>Most diseases are in between and have to be evaluated case by case, not buckshot.<p>You may be particularly interested to hear that there’s little evidence to support regular checkups in most adults beyond blood pressure testing and cervical cytology.<p>> Given the lack of favorable evidence and the potential adverse effect, primary care providers should consider the fact that general health checks, beyond the screening interventions shown to have benefit, likely have little or no effect on important health outcomes. Some of the interventions with demonstrated benefit have sufficiently large effects that a uniform application is warranted (blood pressure measurement and cervical cytology screening). In others, the trade‑off between benefits and harms is so close that patients should be involved in fully shared decision making regarding their participation (breast and colon cancer screening).<p><a href="https://pubmed.ncbi.nlm.nih.gov/31642821/" rel="nofollow">https://pubmed.ncbi.nlm.nih.gov/31642821/</a><p>I suspect your doctor would agree with me. See if they’ll test you for Ebola, for instance. Not because you have symptoms but just cuz.</p>

<p>Several published papers agree. There is in fact little evidence to support regular checkups if you’re asymptomatic.<p><a href="https://pubmed.ncbi.nlm.nih.gov/31642821/" rel="nofollow">https://pubmed.ncbi.nlm.nih.gov/31642821/</a><p>And blood pressure is especially pernicious, basically every doctors office measures it wrong so the results aren’t particularly useful. Many use the wrong size cuff for example, or don’t give people time to relax before a reading. A ton of people have white coat hypertension, high BP only because they’re in a doctors office.<p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC1120072/" rel="nofollow">https://pmc.ncbi.nlm.nih.gov/articles/PMC1120072/</a><p>I saw a paper that showed only 36% of cardiologists did it right.</p>

<p>You’re dealing with populations here. Literally the odds of a positive being false would be over 90%. Much higher in the more rare conditions. I’m not exaggerating. That means every almost every follow up you do is a waste of time, money and limited resources, denying care to those who need it. Including you when you actually do need it. It also exposes you to the risks of unnecessary follow-ups like infection. Your expected outcome is worse this way.<p>The chance a positive is real is so low you may as well just point to a body part and get it biopsied.<p>A positive from this kind of test is statistically meaningless.</p>
