Exactly the first thing that came to my mind. OP may be overqualified for the jobs he is applying for. Your run-of-the-mill AI startup doesn't have any suitable problem for a Ph.D.
Yes, the OP happens to be 60. But there is no reason to speculate ageism based on just that. May be he / she has a 4-page resume. May be he is applying to series A start-ups. May be OP has switched a few jobs in quick succession recently. Too many unknowns to provide any answer.
