To be clear: I think the hype around deep learning is 100% justified (in fact I think it is underplayed).
But in terms of groundbreaking I do think "Zero-Knowledge Proofs for Machine Learning"[1] from 2020 has the potential to unlock some really revolutionary applications in the sense of "things that were not really possible without it".
There have been strong deep-learning contributions to control, but I wouldn't say control is dominated by deep learning at this point. For instance, take a look at ICRA 2022 awards for "Outstanding Dynamics and Control" and "Outstanding Locomotion".
But in terms of groundbreaking I do think "Zero-Knowledge Proofs for Machine Learning"[1] from 2020 has the potential to unlock some really revolutionary applications in the sense of "things that were not really possible without it".
