If you wanted to go back and do a PhD in ML, with your work experience you would be a great fit for the NSF Fellowship called CSGrad4US that supports engineers going back to research. https://www.nsf.gov/cise/CSGrad4US/ You have to be a US Citizen, and commit to a U.S. based university and in a CISE department (this is most CS departments). I am in the fellowship now and highly recommend it! Happy to answer any questions.
