so I optimistic bus about us as a community being able to discover something better yeah I am I think I think we likely will find something that works better you could imagine things like having stacks of models where some of the lower level models predict parameters of the higher level models and so at the top level you're not learning in terms of literally calculating gradients but just predicting how different values will perform you can kind of see that already in some areas like Bayesian optimization where you have a Gaussian process that
