This might not just be a disaster for Google - it could be a disaster for software everywhere. If APIs become copyrightable, what happens to any open source software the implements a proprietary API?

relax, its 2020 so now lets just enjoy how "crazy" this whole thing can go to and finally if Oracle wins... we RIOT, won't end well alright
