Silicone hoses were once an option on police vehicles, I'm not sure if this is still the case. GM had the classic light green and Ford had the baby blue hoses. You couldn't use constant tension spring clamps with them, I guess they would eventually end up tearing into the hose.
That being said, regular rubber hoses tend to last a decent amount of time before requiring replacement. For a vehicle that is in constant use, the five year mark usually does it for my neck of the woods before the hose is all swollen at the connection points. At some point, it's swollen enough for the clamp to cut into it, and you don't want to get to that point.
Worth mentioning, however, I am just replacing all rubber coolant hoses on my '99 Ford Explorer. Granted the vehicle is 22 years, it's low mileage and hasn't seen high heat driving conditions all that much. While the hoses can still remain in service, it doesn't cost much to do when you're replacing a thermostat housing, thermostat and a water pump.
