I think Atheism is the necessary conclusion when looking at this mechanical, meaningless world.

The meaninglessness of existence as always is a value judgement or subjective opinion which can't be proved one way or the other but isn't the mechanistic aspect of the Universe itself proof it is the creation of an intelligence?

I may be misunderstanding your use of the term in this context but personally for me that was one of the reasons I started to believe in at the very least a Deistic type of God based on the fact that the Universe is so finely tuned and for lack of a better term 'mechanical'.
