No, of course not. Neither is AF or AE, and I got along perfectly well without either of them for a long time. I still do, when it suits me.
The technology is available and it's entirely up to you, as an individual, whether you want to use it or not.
I'm thinking about buying a Canon 70-200mm f4, and I really can't afford the IS version, which is expensive in South Africa. I asked my dealer, who is also a professional wildlife photographer, if using higher ISO was a viable alternative. His reply was "Sure. The IS version is great if you can afford it, but it won't stop motion (obviously) and you don't really need it. Wind up the ISO or use a tripod, bean bag, the branch of a tree or whatever". This seems quite sensible.
