I’ll say this, as an engineer who’s worked closely with the brass tacks, a lot of the time when new directors or c level people are brought in, they want to own a space. There was a solution existing prior to them, because the company already existed before they joined. But no one wants to be the guy who supports the previous ideas (maintenance on an engine isn’t as sexy as designing it) because the idea doesn’t have their branding. They want to be seen as bold/innovative, etc. So they make some calls and they find a solution that promises everything they have and more. If the new solution is a success, their position is cemented, they are now a stakeholder in the company. Sales guy is going to sell his ass off, maybe the workforce has to be repurposed (need more expertise in new fields), etc. All this creates unnecessary work for people with real jobs just because a boss wants it. In the end, the new director/c level can say, “wow, this was great, look at how our metrics have improved, all thanks to me!” Despite the fact that they weren’t given all the features they were promised, or they didn’t hire/train specialized engineers to truly own the new solution. Or maybe the solution isn’t very effective. A lot of the time it’s mostly politics. People are trying to get headlines just like politicians so they can keep climbing the ladder.

The way you’re describing “bullshit” jobs doesn’t exist, there are no jobs that are inherently, always bullshit. There’s just bullshit work, and a lot of people who’s job it is to do bullshit work
