What Hacker News says?

  1. Of course people would scramble, but it has nothing to do with how much value you can screw users out of using advertising, because even if ads were worth $0 revenue, search is so valuable you could just plain charge users. This is why there is essentially no relationship between the value of search and the ad revenue. The value of the ad revenue could be $0, and the value to the user would still be $100+/month. And…

  3. Google's problem is they've virtually nothing (given their resources) to "commoditizing their complement". https://www.gwern.net/Complement Google's compliment is web sites. What have they done to make a web site easier to make? They even killed their RSS feed. They have released a bit of web tech, but their offerings are generally a bit sad or only solve Google problems (e.g. Go). If you want to distribute an .exe…

  5. Try and read Borges’ essay on blindness. Some excerpts: There were the books, but I had to ask my friends the titles of them. I remembered a sentence from Rudolf Steiner, in his books on anthroposo­ phy, which was the name he gave to his theosophy. He said that when some­ thing ends, we must think that something begins. His advice is salutary, but the execution is difficult, for we only know what we have lost, not w…

  15. This is in line with "Programming As Theory Building"[0] (Peter Naur, 1985) that puts forward the idea that when one is building a system one builds a "theory" (in a sense a mapping of what, where and why) of that system that is essential for continued work on it. Once I internalized this idea it helped me make sense of why rewrites are not "never a good idea" and simultaneously why they are so fraught with peril, a…

  19. They're commoditizing their complement [0][1], inasmuch as LLMs are a complement of social media and advertising (which I think they are). They've made it harder for competitors like Google or TikTok to compete with Meta on the basis of "we have a super secret proprietary AI that no one else has that's leagues better than anything else". If everyone has access to a high quality AI (perhaps not the world's best, but…

  21. > LLM just complete your prompt in a way that match their training data. They do not have a plan, they do not have thoughts of their own. They just write text. LLMs have a million plans and a million thoughts: they need to simulate all the characters in their text to complete these texts, and those characters (often enough) behave as if they have plans and thoughts.

  25. The problem is that if the law is arguably unethical or arbitrary, you're going to catch more "good" people in it. My comment was not so much a defense of Ross as it was an accusation against unjust drug law. Imagine a hypothetical law which arrests anyone who trades in red shirts. Someone comes along and doesn't see what the big deal is and decides to trade in these shirts on the black market. Lives are saved becau…

This is why I went so far as to make a hand-specific dataset ("PALM" https://www.gwern.net/Crops#palm which of course now everyone is going to confuse with 'PaLM'...). Hands are just way too variable to learn easily.
