While I understand Ageism exists, I do see a trend change though. Take for example all these technical tracks in many companies now. All of these engineers are very tenured and usually very experienced(40+). In-fact they are considered irreplaceable by management since they set the vision of the company. Especially in the valley, the trend I notice is that you don't want to lose these "senior staff, staff engineers etc."
