Could these problems be solved with bigger networks, or do you really need to improve the algorithm beyond that?

No, not really. The "structure of the world" such nets learn is based on bottom-up processing of data -- moving from basic features such as orientations and colours to more complex features. As a result it will make famously absurd predictions like mistake a spotty fur coat for an actual leopard, since it has no "model" of a leopard, in the sense people go "this is an absurd place for a leopard to sit so it's most ceratinly a fur coat rather than an animal". Or to use use a more technical term, no prior probability of a leopard given observed data. Hence a standard convnet (if there is such a thing) will massively overestimate the probabilities of such "adversial" stimuli.
