Most I talk to simply see it as the changing climate of employment, especially in the tech sector. We're all explorers and we like to move from thing to thing. It may just be a product of the industry, but I doubt I'm simply an outlier.

I didn't say I agreed. I just said that that mentality existed. I think long stays in established areas leads to organizational rot and lore accumulation as information and expertise is sunk into an individual (this could be mitigated by migrating around a company every couple years and forcing lore to be written down and documented).
