Just the company that profits from the drug telling you the drug is fine.\n\nYou would never accept that.\n\nNow look at AI.\n\nThe organisations leading the global conversation about AI safety - writing the guidelines, setting the standards, advising governments - are almost entirely the same organisations building the most powerful AI systems in the world.\n\nOpenAI defines AI risk. OpenAI builds the AI. Google DeepMind defines AI safety standards. Google DeepMind builds the AI. Anthropic talks about responsible development. Anthropic builds the AI.\n\nThe people grading the exam are the people who wrote the answers.\n\nAgain - this is not a conspiracy. I'm not saying these people are evil. Some of the most genuinely worried people I know work at these exact companies. Smart, well-meaning, seriously concerned people.\n\nBut good intentions don't fix a broken structure.\n\nAnd the structure is broken.\n\nIn every industry that has ever caused serious public harm - pharmaceuticals, tobacco, aviation, nuclear energy, finance - the pattern is always the same. The industry defines its own safety standards. The industry assures the public everything is fine. And then something goes wrong that independent oversight would have caught.\n\nWe are doing the exact same thing with the most powerful technology ever built.\n\nAnd the defence is always the same: \"trust us, we're the experts.\"\n\nThey were always the experts.\n\nThat was never the point.\n\nThe point is who watches the experts.\n\nAnd right now the answer is: mostly the experts themselves.\n\nDoes that not bother anyone else.",

    "selftext": "Hi all, I created a 100% automated bot back last summer, and it has returned 140% paper-trading since then. This week I bit the bullet and it began trading on real money, £1000.\n\nI have programmed in automatic bet size increases for compounding, so there is nothing i need to do manually at this point. In fact, I am only aware of a trade when it closes and being sent a notification.\n\nThe bets it takes are pretty huge. Risk is usually 5% and reward around 10%. It days trades us100 and uk100 exclusively.\n\nIf (when) drawdown hits 50% of previous highest account value, it will cut the bet size in half and continue.\n\nThis is a bit of fun. I always hear how you need to be conservative with your bet sizes and risk max 2%, so we will see how this pans out.\n\nIt takes around 200 trades per year, so i am expecting an account halving once per year. If the performance of my paper trading account continues, I can expect around 250% per year (that 140% should be nearer 200 due to some technical issues which have been resolved), which when compounded is 10x.\n\nSo when starting with £1k, it would take 3 years to reach a million. Let's have a couple of years added in for leeway so we will make it 5 years in total.\n\nI believe this is a fantasy many traders have when they start out, that within a few years if they can just compound their gains they can get super rich. Well, now I am doing that experiment with real money, mostly for some fun and entertainment purposes, so please don't shit on me.\n\nI'll post here at the end of the week if anything interesting has happened during the week.\n\nEDIT: just to clarify, the first image is live forward-testing results from the last 8 months. The second image is my live real-money account linked to this bot, which I opened a couple of days ago.",

You finish faster, but think harder.\n\nThe bigger issue is creativity. Constant AI interaction keeps the brain noisy, while real insights need quiet, low-stimulation moments to emerge\n\n**So?**  \nAI works best as a thinking partner, not a task dump.
