I think it may come down to computers that obey the Church-Turing thesis, which is finite and bounded. Hofstadter's book *Godel Escher Bach* has a chapter Bloop, Floop, Gloop where the Bloop means bounded loop or a halting program on a Turing machine. Biology however is not Bloop, but is rather a web of processors that are more Floop, or free loop. The busy beaver algorithm is such a case, which grows in complexity with each step. The computation of many fractals is this as well, where the Mandelbrot set with each iteration on a certain scale needs refinement to another floating point precision and thus grows in huge complexity. These of course in practice halting because the programmer puts in by hand a stop. These are recursively enumerable, and their complement in a set theoretic sense are Godel loops or Gloop. For machines to have properties at least parallel to conscious behavior we really have to be running in at least Floop and maybe into Gloop.
