Computers!!! Is it really work?

Been 2 years of 'work' in software industry and lately 1 question has been ringing in my ears!

The question is, 'Is working in a software industry really qualify as work?'

Don't have an answer to it but I have been thinking a bit about it...

All I do is to write code... I don't think its work. Work should yield something physical that you see developing into a product. On the other hand in software, you see a final 'product' that again runs on the same computer. Nothing physical, no identity of its own...

Dunno what I mean by all this, just that for the past few days, I am very skeptical about my 'work', if that is indeed what I do.
