Your list is missing some high profile products like Google Allo and Chromecast Audio.

News and weather is basically just merging with another app, reply moved into Android (I beta tested reply, and despite the app being gone I still have the features), Tez still exists as a part of pay, showtimes got rolled into normal search, tango was experimental and became arcore, google x very much is still around, glass never left beta as a consumer product and is still relevant as an enterprise product. Chrome frame has no reason to still exist, Quickoffice merged with Google docs, the Nexus line became pixel, noop was a 20% project, not an official google product.

When you remove the garbage, you end up with a company that deprecates a few things each year, most of which you've never heard of anyway.

chromecast's ux was always waaaaay to complicated to understand for non-tech people and audio is it's first casualty.

Allo is overhyped, from day 1.

I recognized and could explain more than half listed, but only cared about a couple (didn’t care about Reader).
