Already many of our cellphones and computers contain what I call "Frankenstein chips" where manufactures stack them like so many Legos, often next to each other as well as on top just because its cheaper and you can do things you can't on a single chip. What's these guys discovered is a new way to conceptualize the problem as one of communication between self-assembling layers. In effect, they can provide translators in between layers which is something that bacteria do with all of them essentially speaking different variations on the same quorum sensing pattern matching language. For bacteria it means they can talk to distant relatives explaining how many of them acquire immunity they shouldn't have. Using this same kind of linguistic systems logic that blends into the physical our own mind and brain self-organize so that, on the most fundamental level, they can substitute for one another's role in a pinch or even if it just happens to be more efficient. In a universal recursion of the law of identity everything would be self-assembling in some contexts and everything would obey pattern matching rules which, once mastered, means we could predict how to make any number of self-assembling things including printing out TVs like so many newspapers or whatever.
Already the first self-assembling quantum computer chip has been produced and people are rushing to use it to build the first full scale quantum computers. Within five we should have at least a fifty qubit quantum computer and within ten perhaps 300 or more which is about as ridiculous an amount of number crunching power that anyone has any clue what to do with. Theoretically, an AI can be self-assembling as well and we just need more powerful computers to crunch the numbers or researchers to keep making these kinds of discoveries.
