Well, by definition of Singularity and when looking at technological advancements, I would say we are in the midst of one and have been since cell phones.

Singularity - "A hypothetical moment in time when artificial intelligence and other technologies have become so advanced that humanity undergoes a dramatic and irreversible change."

Outside of AI currently, you could say we are already at a point of no return. Can we return to life without cell phones, computers, or the internet? Not really. Our entire society would collapse if those went away. Just those three alone have had a dramatic impact on our community. The only thing missing is people's interpretation of AI.
