I definitely can relate to Point 4. I think one way of countering this is to focus on a platform versus the base technologies. In particular, I am thinking along the lines of doing development work with the likes of Salesforce, Microsoft Dynamics or SAP. The years of experience are valued more and the rate of change is inherently slower. The obvious downside is that the development work itself may not be as interesting but that can be mitigated somewhat on the projects one takes on within these platforms.
