I think UX designers have already caused enough havoc, we don't need more of them
Of course, the more you scale design, the harder true talents are to find. That doesn’t mean the profession is useless. Also, developers caused a lot of havoc as well. Nothing that goes wrong today has been put on the market without developers. That doesn’t make them useless either though.
Of course, there are many situations where users can’t use competing software, or where there is no competitor. This leads to resentment, and I believe some of the negative sentiment against some UI/UX designers comes from people being burned by bad experiences caused by UI/UX being optimized for the interests of the company instead of the user.
