I don't know about the Silicon Valley, but I'm in the Silicon Forest (Hillsboro/Portland Oregon) and this market seems to be very merit driven. You can be 80 years old and get a job if you can do work. Maybe you can't get a job at fart.IO building an API for some craft beer BS but at many mid to large companies 40 is still an average.
The last 4-5 companies I've been at value bullet points over anything else (for what that's worth). If you're 40+ and coming in showing off your PHP skills, JQuery or WinForms experience you'll get dumped, but the same goes for the 23 year old with that skill set.
My advice is always the same for developers my age: Keep with the times! If you aren't passionate enough about this work to continue learning and advancing on your own time get out. Go do something slower paced. Don't expect the industry to change.
