"Retail investors have a well-established track record of destroying their own wealth. Studies have shown that individual traders somehow have the opposite of skill — they manage to do worse than they would by picking stocks at random."

These finance guys don't understand what's really happening. The retail investors are high stakes gambling on purpose trying to get instantly rich because some guy on whatever telegram, discord or whatever is bragging how he got rich gambling on some ridiculous asteroid mining futures stock. No amounts of 'but look at this data...' will ever change their mind. No amount of telling them that low latency trading outfits like Citadel receive these retail order books in real time and then buy/sell the stock to retail traders making a profit, literally sniping their trades, will make them change their mind either.

Nobody wants to invest anymore in something that returns modestly in 30+ years they want to be rich now then run some YouTube/TikTok channel how you too can become rich like they did gambling.

For me any kind of freelance Toptal like site needs to be specific about hours they expect you to be available as most people will be doing it P/T after school, or whatever other job they're doing. There is of course the problem with clients not paying, then your site is on the hook to pay the developer.

Now we have non-convex neural network models which require non-convex optimization which to me (again a pleb take) is just tricks of the trade from complexity theorists adapting the principles of convex optimization to things like gradient descent in deep learning by observing continuous local smoothness of the training objective at the stability edge thus some convex optimization can be used.

Why it's not taught instead of the confusing intro courses I'm sure have their reasons but it's another example of following what the universities teach in undergrad is not always the best road map for self-learners.

Shorter than a book, and not 30+ hours of watching lectures.
