AI displacing jobs will become a reality very soon. As an employer, I can say that this is real and not just hypothetical. It will start from companies opening fewer new headcounts for white-collar jobs. Then, it will be hiring freezes. Next, vacant positions will not be filled and those headcounts will be trimmed. Lastly, it will be layoffs. Many white-collar jobs (any job that is heavily computer-based) will be lost. After the first wave, the second wave starts when humanoid robots are mature, many service industry jobs will be gone too. Then, AI + robots will go after blue-collar jobs as well.
In 5-10 years, it'll be extremely hard to find jobs that cannot be done by AI + robots. What will smart people do when they can't find jobs? Yes, they will invest. That's the only chance of growing your income. People will invest in companies that drive AI and robotics, because they will have first-hand experience in how their lives have been impacted. I'm not a pessimist, I'm just a realist. I know what AI is capable of, and we all have to be prepared for massive societal changes.
