I see the advent of modern corporations as the start of independent agents competing for resources and striving for their own goals. It also is when we started seeing the exponential growth that defines our current age, and while there were many other factors that played into this growth, it's a convenient marker. The standard thought is that the singularity is the moment when the speed of exponential growth outpaces the human ability to process that information in real time. I think that definition is too human-centric, and I'd rather refer to the phenomenon of exponential growth as a longer continuous process.

So the formation of LLCs was the start of the Singularity, and we haven't seen the end yet. Like I said, non-standard and weird.
