here's my hot take: the Stadia will not drive Sony, Microsoft or Nintendo out of the console business. The industry is slowly changing and this is just another small step towards games as a service, but all the major players will learn to adapt and survive, even Nintendo imo. Whether Stadia is an actual success will remain to be seen. Only Google knows what goal they have for it and whether it is considered a success internally. Maybe they are just getting their feet wet, or trying to brute force their way into the industry. Remember, Msoft took huge losses on the original Xbox.
