Thanks to @coolish (Wei Shen) for giving me this traffic! This topic made me realize once again that this is the next era where ordinary people have a chance to turn their lives around, not limited to any particular circle. Wei Shen posted two questions, which are extensions of his experience gained from hundreds or even thousands of trades. Normally, if you can understand the meaning behind these questions, you're either a one-in-a-million genius or someone who has undergone countless trials. But what is the price? Losses from trading, mental anguish, life pressure, and so on. Previously, my evaluation of online "riddlers" was "pretentious" and "affected by profound knowledge." But in a non-professional setting, an effective summary is concise and brief. How can you understand the underlying principles without that experience? Now, countless online "riddlers" allow you to use AI to explore whether there's any real substance. AI is the free mentor, teacher, assistant, and other "people" of this era who can impart knowledge and simplify processes for you. In the past, learning anything required payment. Now, with a plethora of open-source and commercial LLM programs available, ordinary people can learn at low cost with just a mobile phone or computer and internet access. Previously, opportunities and mentors were crucial; now, AI can help with almost anything. AI isn't omnipotent or 100% accurate, but are your teachers, colleagues, and assistants 100% accurate, especially considering the human element? AI can be your first teacher; it will make mistakes, but at this stage, it's an excellent teacher for the average person. Once you've mastered it, it will become your partner or assistant. In this era, all you need to do is work hard and change yourself.
