Yes, in fact, some people at the time declared the tank dead for the first time. Trench warfare was a thing of the past, and so the question arose as to why we would still need a vehicle that had only proven its worth through trench warfare (the first tanks were designed to break through heavy defenses and, in particular, to eliminate machine-gun nests).

These commentators were even correct in that the subsequent wars were no longer trench wars, and the tank diversified beyond its role as a breakthrough vehicle, evolving (among other things) into a system of one-on-one combat over the course of the next major war.
