Mitzius. There is no Chiyuv to go to Goyim to learn Chochma, unless it is needed for Limud.
For example, part of the whole Anaskis policy was changed due to data from the CDC. That was unavailable without “Goyim”, so it is a chiyuv to learn it to be able to paskin (and for the mitzva of “Lehavdil” between Kosher & not).
