I think it depends on how you define "job hopping". I think that very short tenures (something less than 2 years or so) were rarer then than now, but I don't think that anything over, say, 3 years is what I would even call job hopping.

I think 3 years is plenty of time to hone your skills, grow in an organization, and get exposure to multiple different projects or teams. After that, I don't think anyone would begrudge you for leaving for a better opportunity, now or in the 90s.
