I would argue this is well discounted by level of investment made against the future. I don't think the winter depends on the amount that somebody makes today on AI, rather on how much people are expecting to make in the future. If these don't match, there will be a winter. My take is that there is a huge bet against the future. And if DL ends up bringing just as much profit as it does today, interest will die very, very quickly.
This is analogous to the way electricity took decades to realize productivity gains in the broad economy.
That said, the hype will dial down. I am just not sure the investment will decrease soon.
So I guess we're waiting for something similar to happen with AI and then get AI 2.0?
The current road infrastructure (markings, signs) has been designed for humans. Once it has been modernized to better aid the self-driving systems, we don't probably need "perfect" AI.
The difference between the current AI renaissance and the past pre-winter AI ecosystems is the level of economic gain realized by the technology.
The late 80s-early 90s AI winter, for example, resulted from the limitations of expert systems which were useful but only in niche markets and their development and maintenance costs were quite high relative to alternatives.
The current AI systems do something that alternatives, like Mechanical Turks, can only accomplish with much greater costs and may not even have the scale necessary for global massive services like Google Photos or Youtube autocaptioning.
The spread of computing infrastructure and connectivity into the hands of billions of global population is a key contributing factor.
