The future of the stock market is still up in the air, but it's safe to say that the market is not futureproof. That's because the current market design is not sustainable. The current stock market design is based on the idea of "asymmetric demand." This means that if one company is in high demand, then other companies are guaranteed to be in high demand as well. However, as soon as one company becomes popular, then all other companies are guaranteed to be popular too. This means that the stock market will always be a one-way street.
