Oh, man. Unbelievable cluelessness coming from the MIT Tech Review, of all places.
It takes all that carbon to research and develop a breakthrough advance like LSTM.
Once the breakthrough is made, everyone can use it in a thousand different ways.
Merely training and tuning that model uses less power than your air conditioner does in 10 minutes.
And for those unfortunates who can’t afford a GPU - places like Kaggle offer them endless GPU time for zero dollars and nothing cents.
Compared to other industries, AI Research and Development has one of the smallest carbon foot-prints. Any other field - say biotech - uses more carbon just during the morning commute of its clerical staff.
