Not a very suitable analogy because an animal brain was in fact optimized for mobility for hundreds of millions of years. The real difference in desktop vs. laptop is lack of optimization for expandability, for use of standardized components, for ease of physical access for upgrades. Now that I wrote previous paragraph, it leads me to question whether these 'no-brain' cases may be less fit for future rewiring? For instance, being transplanted in a different culuture, different language, different field e.g. physical work or arts or social work instead of intellectual or from arts of physical work to social or intellectual work?
