My cable system is 35 years old. Well oiled and lubed. It's as good as the day it was installed.
Any hydraulic cylinder will need new seals long before 35 years. As long as it's a name brand it is just routine maintenance.
Autopilot electronics are a mystery Can last 35 years, or fail in 6 months. In general I think they are very reliable.
