The recent advances in machine learning were mostly achieved by the hardware, and the hardware is said to continue driving the development of AI, but I was still shocked by this thread which reads that the most expensive and largest model would cost 1B dollars in 2025. And I learned that universities are suffering from an academic AI brain drain partly due to the scarce hardware resources.
Some people proposed the so-called Green AI that encourages sustainable AI development but provides few constructive methods to prevent the trend.
I wonder if the redder and redder AI would be in fact truly inevitable. It seems to me that all companies should build an expensive compute infrastructure to be competitive, but I think the investment would be very risky since most companies cannot get a higher return.
But on the other hand, we human beings have evolved tens of millions of years or billions of years(life) on earth with hundreds of billions of brains that have ever lived on earth as a whole "human brain". The biological wetware seems much much redder than the nowadays hardware and has consumed much much more energy than all the supercomputers. To make machines as intelligent as we humans shouldn't we pay as high a price? It reminds me of the NFL theorem but it should be imprecise in this scenario.
So, will there be some promising techniques on the algorithm side that can make AI greener, affordable and sustainable in the future? If not, could anyone please explain why AI should be unavoidably red and inevitably redder?
