I absolutely don't agree. Exactly how does wanting to know more amount to squandering life? I think the beauty of philosophising about questions like what is reality is that while we may never directly come to a definite answer, in our attempts to approximate a definition, we come to answer other questions that benefit us in life in ways that we couldn't have foreseen otherwise. Philosophising about what reality is is pretty much the fundament of every philosophy that exists, and ever has existed, because it is the absolute, the ground on which everything else stands, and without a reasonable approximation of the soil you're building on, it's going to be difficult to construct a world view that you can feel sincere with to follow. These questions have spawned art styles, world views, a better understanding of what quantum mechanics might encompass, approximations to explain what purpose we want to create for ourselves. I am sure that not everybody feels they should keep themselves occupied with what reality is everyday, and I won't propogate that we really ought to sit in a corner and think about reality like a bunch of passive nihilists, but to call thinking about matters like this squandering, claiming that those who think about this are ruining the beauty of it, or saying that people shouldn't ever really bother talking about this or whatever, is seriously apalling. Just think about it, without this question, we wouldn't have half the amount of art that we do now, and half the amount of keen scientists working on discovering and giving meaning to parts of the universe that had fallen out of our bubble of assigned meaning to a vast pool of untapped knowledge before.
