Earlier quoted context omitted.
No, not at all. It isn't really about age. I've dealt with "hipsters" in their 40s and 50s who've come up with very bad UI designs. Likewise, many of the managers or executives advocating for these redesigns are in their 30s, 40s or even 50s. While it may be more of an issue with younger people due to a greater lack of experience and intuition, it's a phenomenon that's quite independent of age.
> These people are often relatively young, often have limited experience > "hipsters" in their 40s and 50s These statements cancel each other out, so there's no reason to state either as supposedly providing information content.
A 40-year-old who got into web design after a lengthy career in print media design, if not some totally unrelated field, is often no more experienced than a 20-year-old who got directly into web design. I know this can be true, because I've worked with both types of people in the past.
And "often" does not mean "always", obviously.
