Good software is very persistent. Client doesn't care about underlying technology as long as it performs. Freelancing for 20+ years I have active sw written in VB6 that still sells after 18 years. Nowadays wherever I start a new project (web of course) I try to pick mature, fresh (if possible open source) frameworks, components etc. since you simply never know how long you're going to maintain it.
