Still seems pretty optimistic to me. Twitter's institutional engineering knowledge and relationships with its customers, i.e. advertisers, have all been set on fire. It's unlikely Twitter will fully die, but I can't see how, next time anyone gets to sell it, it will have even a quarter of its original value. And Musk isn't likely to cut his losses, seeing how his actions up to this point have been driven by hubris. He's going to ride it all the way to the bottom. I expect it to go for pennies on the dollar.
