Sure, but none of that was developed by dod in any real way. A litmus test to consider is that the dod still halls belig ml problems but you don't see phds funded by dod going to the dod. The good ones all go to industry because they know thier reseaech stops as soon as they start working for a contractor or warfare center. The money excuse is just a patsy. The government has plenty of money to pay these ppl if they can produce which they do well in industry. It's simply not a focus of darpa to do basic research in learning and intelligence in a meaningful way.
