> I was really worried that I wasn't producing like I should at my seniority
This is precisely the effect I'm describing. For most tech jobs, especially at higher levels, the generic tech knowledge can be a fraction of what's necessary to get a job done. Thus people notice a drop off in their output and freak out. A good senior engineer will pick up the new things quickly, but one can't expect to replace 10, 15, 20 years of hard earned wisdom in a month or two.
