I changed my default search engine to neeva just a couple days ago. Unfortunate since I really liked their product. The team probably has a few domain experts in generative AI and infra at this point, and so they can make or raise more money by pivoting completely to direction.

this is a shitty analogy

AFAIK, the new Photos app in iOS and OS X are built on CloudKit. So I assume it will only die when iOS dies, which could be another decade or so.

Well, that's not much reassurance because they stopped publicly selling/supporting WebObjects long before they stopped using it themselves.

Pretty sure they still use WebObjects for iTunesConnect (at least).
