You're talking mostly about the aesthetic part of fake meat, but there is another huge advantage over existing products which is health/environmental. Current vegan/vegetarian incarnations of fake meat (Boca, Morningstar etc.) are typically actually not that healthy in terms of protein/amino acid content and sort of end up being eating a cake made of grains.
The ability to create, cheaply, a high protein, high calorie, amino acid packed product, regardless of whether or not it is aesthetically pleasing, could have massive impacts on our ability to support the human population of this planet, in a way that existing meat and vegetarian solutions do not.
