When the video showed the slide saying "Life is ____" I paused and thought about it for a minute.

For me life is producing output when presented with some kind of input. If we are alive and that's pretty much what we do, life must be it. (not only man, but every animal I can think about)

Now, how are we alive and a computer problem isn't, I don't know. Maybe because our input comes directly from the natural world?

What is the meaning of life? As others said here, it's a question that seems illogical to be asked.
