<p>This point naturally leads to a more general discussion.<p>If AI can do everything and gets everyone out of jobs, who is going to consume the ‘everything’ produced by AI for someone to pay for the AI?<p>I don’t think UBI is a real solution, it’s too hand wavy.</p>

<p>This is why republicans get votes.<p>If you pull nonsense like this in a two party system, there are enough people with blind spots that it tilts the results against you.<p>My favorite example of such a blind spot is a friend being flabbergasted that someone funny could be evil.</p>

<p>For sure, it makes sense for nice well defined problems that execute in isolation.<p>Think of the situation where the string search is running on a system that has hyper threading and a bunch of cores, and a normal amount of memory bandwidth.<p>It'll be faster, but at the same time make everything else worse if you overuse vector instructions.<p>(also cherry on top: some modern CPUs automagically lower the clock when they encounter vector instructions!!!)</p>

<p>The comparison is often just plain old linear code.<p>For example, one simd instruction vs multiple arithmetic instructions.<p><pre><code>  x1 += y1
  x2 += y2
  x3 += y3
  x4 += y4
  </code></pre>
We have fifty years of CPU design optimizing for this. More often than not, you'll find this works better than vector instructions in practice.<p>The concept behind vector instructions is great, and it starts to work out for larger widths like 512 bits. But it's extremely tricky to take advantage of that much SIMD with a compiler or manually.</p>

<p>Go on, give it a try for a few days.<p>My point is equally valid for "markets consistently value 'yes' too highly".<p>The occasional 'no' will wipe you out on average.</p>

<p>SIMD performance in modern Intel and AMD cpus is so bad that it is useless outside very specific circumstances.<p>This is mainly because vector instructions are implemented by sharing resources with other parts of the CPU and more or less stalls pipelines, significantly reduces ipc, makes out of order execution ineffective.<p>The shared resources are often involve floating point registers and compute, so it's a double whammy.</p>

<p>> It's not like CPUs are slow, in fact they're quite a bit faster than any single GPU thread.<p>This was overwhelmingly true ten years ago, not so much now.<p>Modern GPU threads are about 3Ghz, CPUs are still slightly faster in theory but the larger amounts of local fast memory makes GPU threads pretty competitive in practice.</p>

<p>Leverage is not the steamroller here.<p>It’s the 90% chance of making 1$ vs 10% chance of losing 100$.<p>The exact numbers vary, the expectations even out with high volume stocks but prediction markets do not because of rounding that favors the house.</p>

<p>Oh no, it's not pointless. It's just doublespeak.<p>It exists so there's a way to respond to demands like 'no criticizing Israel', or 'Taiwan is an inalienable part of China's territory', or double negatives like 'no not agreeing to automated droning'.<p>Because if you do not have a way to agree with these, your business can and wil be targeted and shut down.</p>

<p>> Whether it's pennies in front of a steamroller will depend on […] many other variables.<p>No, all these variables cancel out.<p>If you were picking and choosing, yes. But this approach is basically betting no on all the markets.<p>The textbook explanation of this is the central limit theorem, proving this mathematically is a bit more involved for power-law systems like this but it’s empirically valid.</p>

<p>Don’t be gullible enough to fall for this bad math.<p>Say 70% of the time it resolves to ‘no’, you still don’t make money by blindly choosing ‘no’.<p>Guess why?<p>Hint: This strategy is also described with the macabre analogy: picking up pennies in front of a steamroller.<p>Do you want to pick up pennies in front of a steamroller?</p>
