As we saw with the example of search engines, a new competitor may split an existing market, only to have it later converge on his product, because he made something people liked. If they manage to do that, it might just get downloaded by users, mandated by companies, and shipped with Linux desktops as the default interface. It's made by Google, and the idea has been around for a decade, so I take it as not impossible that it could be that good.
