Time to go into entrepreneurship?

I've been in the industry for 2.5 years. I wanted to make this a long-term thing, but it seems like all that I've heard for the past couple of years is about how my job is going to get offshored and/ or replaced with AI. I figure that if you need to deal with this much stress, worry, and effort just to hold a job, why not manage the same level of stress to build something for yourself that you own completely? We already know that tech companies massively underpay their devs, even in the US where salaries are the highest. Google makes $2m per employee. Apple makes $2.5m. Even the highest tech salaries pale in comparison to what these companies are making off of their devs. Why not just say fuck these companies and take a swing at making something of your own? I don't see the point in accepting a pay ceiling and making the tradeoffs that an employee typically makes for "stability" when these jobs aren't even stable anymore.
