No one can rule out this sort of speculation, of course, I see no fundamental reason why life could not exist as some form of energy (whatever that means), or as some process occurring in a physical substrate but not actually a part of it (like software running on a computer, it's the software that's "alive", the computer is just a necessary component.
Perhaps social insect hives are "alive", in a way the individual insects are not, as we have speculated about here before.
However, as far as we know, one of the self-evident characteristics of life is great complexity, and as is clear, the greatest potential for open-ended complexity we know of in nature is carbon chemistry in water solution. Even if other types of life do exist, I suspect carbon-based life like we are most familiar with is probably the most common. After all, we know it works, and it seems to be everywhere on this planet, and has been here for over three billion years.
