That's not good enough for investors. Right now, either something is worthless or it is literally the most influential invention in history that must succeed. Even if/when the AI industry suffers a setback, the trend of investors becoming more psychotic will continue. Every additional dollar that they need to extract for infinite growth is harder to get than the previous, so we'll likely see more financial Hail Marys in the future that people will desperately load their money into - maybe the next big thing is what will finally give us more growth again!

What a persistently low interest rate does to an economy. (It completely destroys it via this process.)
