It does not at all compare. The whole Coral/edge TPU project was the idea of a guy at Google (https://www.linkedin.com/in/billy-rutledge-1b750a4/) who never did anything interesting with it except a series of press releases and various hardware drops and demos). It has nothing to do with google's real TPUs. I still don't understand why this project has been allowed to live while talented engineers and projects were cancelled.
I don't get the impression Google has invested much more into Coral beyond the initial set of products.
In terms of longevity - it's kinda table stakes in the electronics industry. Nobody's going to integrate your edge AI chip into their smart CCTV camera or whatever if you can't promise 5+ years of availability. There are chipmakers still selling parts they launched in the 1980s.
