In your opinion, what would it take for the U.S. Economy’s AI “bubble” to finally pop?? What type of upcoming hypothetical event would need to take place? Is it even a bubble at all? Will it ever pop? Very curious to hear everyone’s thoughts. I feel like all I ever hear is about how it is a bubble and will inevitably pop, but nobody ever brings up what types of scenarios or potential catalysts could bring about such an event.
