Capitalism has trained us to equate productivity with our self-worth. So please don't feel the need to be constantly busy during the pandemic. You are enough, regardless of what you're building / making / cashing out on.
Having said that, if you're truly interested in a project and it keeps you engaged, go for it and I hope you're enjoying it!!!
I bought historical option data in the past directly from CBOE [0]. Depending on what you need the prices are very reasonable. E.g. for a single symbol ~$70-$80 for a year depending on the interval you need. There is a big discount if you just buy all the symbols.
I cannot recommend the stock prices though. Somehow there were just a lot of mistakes and you can get them from other sources cheaper.
The "Ethical concerns" section in the article feels like a punt. The author quoting "this technology is really about better storytelling" is aspirational -- the technology's story will be written by those who use it, and you can bet people will use this maliciously.
Guilty of that. I've seen friends who are young (14-15) and they talk about work smart not hard, 80/20 and deliberate practice to break through the plateu. Can't tell if I should find it kinda funny or just sad. Business books do ruin social life and makes you very critical of yourself
