Automation technology is not available to the masses. I work on meta models, and we have automated the systems development lifecycle long time ago, still in use today. Limiting the need for programmers. Banks, industry and governments are still running the code we developed in the 80s.Is there any other equivalent of a superpower technology/knowledge that "mortals" have tamed? Medicine? No. Programming? No.
Nothing in our history leads me to think that anyone except people who enjoy it would become self-directed traders.
Most likely outcome is "self-directed" trading through third-parties like wealthfront. So the automation will be concentrated.
As in real life: if everyone is doing something, there's a possibility they are missing an opportunity. In 2006-2008 everyone was on my ass to "buy a house". I already owned a house from university, but I paid $150K for it in 2000. It is supposedly around $1mill right now. I decided to avoid and was able to buy some rental properties that I have since divested and moved into REITs. The return is not that different.
What is everyone doing now? Becoming a landlord. I'm already out of it before they decided to do it. Margins are razor thin. https://www.forbes.com/sites/marcpr...-better-than-buying-real-estate/#3d4d78ffd6b7
So, automation will concentrate but that will leave opportunities that are not scalable for the entities doing the centralized automation.
The same have been done with animated movies. Tools have been developed to limit the amount of drawings.
