In Aaron O'Connell's TED Talk, "Making sense of a visible quantum object" he concludes by saying:

You hear a lot of talk about how quantum mechanics says that everything is all interconnected. Well that's not quite right, it's actually more then that. It's deeper. It's that those connections, your connections to all the things around you, literally define who you are.

That sounds like an end to "objective truth" to me. We are what we are connected to, our perceptions literally shape our reality.
