I am not saying he created by Thanos solely. I am thinking he is perhaps somehow involved. I am past the being angry bit and thinking of how they are going to go about this.
I just heard this nice theory about Ultron being powered by the Power Gem. I think that would tie in well with Thanos without him having to be there the entire time or directly responsible for Ultron.
