That’s such a typical Feynman answer too. charitably he’s doing it because he doesn’t want to misspeak or suggest something untrue from his position of expertise - but it does also come off as being dodgy about answering people’s questions. He does the exact same thing in that video clip where an interviewers asks him how magnets work .
That's just part of the answer, he goes on to say that if you ask questions of nature and don't like the answers then that's just too bad, you don't get to dictate to nature how to behave. Scientists who don't like particular results because they don't match their philosophy of how things should be (most famously Einstein and QM) tend to end up tilting at windmills and not making any more progress.
However, humans can't help having likes and dislikes but I think the trick is to save that for other areas of interest - e.g., art or music or people or activities that you like for entirely subjective reasons.
