In the AI era, you may lose your job, but you will definitely have positions.

Because:
First, AI will break the paradigm of scarcity economics and usher in an era of prosperity; holding positions is key to enjoying the dividends of this era.
Second, there is no strategy that always makes money; complex systems give everyone a chance to become a winner.
Third, human nature is competitive and ambitious; competing with others is endlessly enjoyable.
Fourth, life is a game, and gambling is its meaning.

Jobs will eventually disappear, and trading will be the final game.
