Much of what is left of Quicksilver today is about fixing bugs and keeping it on life support which is why I used the term "fell apart" instead of "dead". This was an app that the developer stopped programming for in 2006 and the bug fixing didn't really start until last year. Th plug-ins to other apps are part of what made Quicksilver great and most still don't work and haven't been updated since that time.

Sounds like a great idea for a kickstarter.

I'd still take "basic bugfixing and maintenance" over "gone completely" however.

I suppose in some sense it's a bit like owning a classic car, the warranty and support from the manufacturer is long since gone but there exists a community of owners and refurb businesses keeping it alive.

The difference with your car analogy is that the car doesn't stop working because other cars are adopting new technology or that the roads became worse. Quicksilver broke once Leopard was released.
