We can look at a machine, as a cold-heartless-soulless construction, devoid of any self-evaluation, self-improvement, or function beyond the purpose it was built for, or we can look at being a machine as being calculated, efficient, and functionally flawless. It has one purpose, and it serves it's purpose, or perhaps it's multi-purposed, and it does all these purposes satisfactorily. If you and I are machines, then we are programmed by our mothers and fathers, instead of by a programmer tirelessly plugging away on his keyboard with a fist full of redbull.

We are extremely advanced machines, but the medium of growth is vastly different than a machine we would design out of electronic or synthetic parts, because the development process is different.

In this case, one can be the other, but not both, where as the other can be both.

A machine can only be itself as it was designed, and nothing else, but a human is both a machine, and a human. What is a human, we may ask?.

A human is an extremely advanced machine that possesses the capability to evolve, adapt, and change itself to meet the requirements of the environment it is in. My laptop can not adapt for the humidity in the air, or the temperature, beyond a certain point, it will cease to function properly; however, I will be just fine, with my 50 coats, and many layers to keep me warm in cold climates. If my hands get cold I'll either wear gloves, or I'll breath on them to temporarily warm them.

So to answer your question, yes, you are a machine, you are an advanced human machine.
