AI Winter was related to neural networks existing but computers not being fast enough to handle the amount of data needed to train them + massive datasets themselves not existing. So far, I'd say no? New models are still being developed and getting better in very short time frames vs what folks did historically. The finance bubble thesis is more related to: "are companies going to generate revenues to justify the massive investments being done?"
