I question what sort of updates you're actually getting. Debian is known for being extremely outdated. This is a major reason for its stability.
Sometimes things change way too much. Sometimes they change in incompatible ways. Sometimes changes come from upstream and there's nothing the distribution can do about it. In these cases, our attention is required. Things break and we need to fix them. We need to adapt.
In order to avoid this, Debian must be outdated. It must avoid updates that break things and this necessarily means you end up using software that's years old. That's fine, it's a perfectly valid trade-off. I'm sure there are a lot of users out there whose wants and needs are perfectly filled by Debian.
If someone's interested in Arch, it's likely because of its huge repository of up-to-date unpatched software. The Arch user must be able to deal with change. Sometimes it's unavoidable and Arch culture makes it clear that users are expected to put such effort into their systems.
