If a museum can include a small portion of a frame around a public domain painting and claim new copyright as a result - surely any smallest spark or creative influence qualifies, including choosing a single word and choosing the model and time and which output is selected does as well.
The idea of work for hire, and the notion of copyright assignment, applies to people and not machines or processes employed in the creation of a work. Your brush manufacturer would never dare try to claim that their creative selection of fibres and thus their contribution to the unique brush patterns in your painting constitutes a creative contribution to your work. Why is a complex digital model which does the same any different?
Perhaps it is copyright as a whole that is wrong and is nothing to do with AI. This is what we get for creating imaginary property as a means to finance speculative creative endeavours in a capitalist system. So, yeah. Fun times there - once again technology challenges another economic status quo.
There’s no way to map DALLE prompts into any kind of obvious picture from the input. Even DALLE itself can produce a wide range of outputs from a single input.
Further, people have programmed in languages before any compilers where created which worked after the compilers where created.
Early CPU’s didn’t compile anything they directly executed the instruction pipeline.
Also, the number of CPU’s manufactured heavily favored very simple designs.
As to your point that’s not what CPU’s do though, they have both a set of instructions and a set of IO with the outside world. A compiler always results in the same output from a given set of instructions, but with CPU’s you can run the same code and get wildly different output due to that IO.
The only way you can call a CPU a compiler is as a subset of its capabilities. If they they have internal microcodes where a given instruction gets translated into a different internal representation, but that’s not the end it also executes those microcodes.
