Just like with any product ever, if the product is popular and produces value, it will stick around. Products come and go all the time, the difference being with Google that since they are so big and have countless products, the company doesn't go away when a particular one fails. Many products fail in this world, but often the company that made the product also goes away, so you have no one to complain about going forward. Google is easy to pick on in this regard.

If this same product was released by a company you had never heard of, would you use it? Would you honestly believe it to have a greater chance of survival?

My suggestion is to simply judge this product on its merits, and accept that nothing is guaranteed, whether it's made by Google or not.
