>>197532363Breathing is just a organic function for acquiring the oxygen we use for the respiratory reaction we use to create energy.
growth is just a function we have that is a result of our reproduction system, which functions by ingesting raw materials and using them to create another human.
If a machine is intelligent and capable of creating more of itself, is it not alive, just because it didn't physically consume the parts for reproduction? If it was efficient I'm pretty sure evolution would have had us pop out of the womb as full-bodied adults.
In addition, robots require energy for sustenance as well, in fact it's pretty much the same energy we use, they just use a different chemical reaction from a specific energy source.
We already have solar panels which harness energy like plants, which under your definition aren't alive.
Point is, you're only defining "living" by what we're familiar with because that's how the ecosystem on Earth developed.
