Humans also think about words in terms of subcomponents, languages make heavy use of prefixes and suffixes for example.

  This is not the same.. The masks are randomized and lossy. Although yes there is potential for a transformer specially trained to segment prefixes/affixes/suffixes, it might augment some of its encoding abilities, see e.g spanbert for a related example of opportunity.

    What do you mean with "lossy"? What information is being lost? Or do you just mean that there isn't necessarily a unique way to encode a given string?

      I mean that information is being lost https://arxiv.org/abs/1906.08237 https://arxiv.org/abs/1906.08237 See xlnet for the rethoric https://www.microsoft.com/en-us/research/publication/mpnet-masked-and-permuted-pre-training-for-language-understanding/ https://www.microsoft.com/en-us/research/publication/mpnet-m... Or mpnet which attempt to combine the best of both worlds information wise but still find that masked modeling is much less useful than autoregressive.
