Thanks for reminding me why I don’t post anymore. 
I’m not looking for an argument nor to be the Debbie Downer of the Google Daydream thread. It feels like your questions don’t have a genuine interest behind them. However I will give some of my time this morning to answering anyway before tuning into the I/O Live Streams today (https://events.google.com/io2016/), in case there is a genuine interest in understanding, buried behind your frustration at Epic; and for anyone else following this thread.
Might not be a bad idea. VR is a competitive industry promising billions in revenue to the lucky who succeed. Epic is making tools available to enable and empower us to participate - yet in the end, if things don’t work quickly enough then it’s up to us to figure it out on our own or someone else will.
I read your other thread on the Gear VR Wishlist. Whiting responded and gave you the best answers that he can. So here’s the truth… some of your list will likely show up before the Fall of this year; some will have to be left to the side; and some of it will likely never happen. Unless you learn the C++ to code it into the engine.
I went all in with the Gear VR platform. Have a Note 4, an S7e, an Innovator Edition and retail Gear VR. Did the deep dive with Unreal, FMOD, Unity and the Oculus SDKs - just like everyone else who did here. I have genuine admiration and respect for the handful of developers from this community who made it onto the Gear VR platform this year and hope that they are succeeding financially. The platform seems much more closed this year than it was last year, with a higher bar to entry, at least for now.
I’m not jumping from platform to platform. I’m searching for a path to success through this industry, for my family and I, while staying above water.
Do the research and decide for yourself.
From my perspective, the difference is obvious and doesn’t need explanation.
Google has been aggregating Search, Location, Imaging, Translation, Text and Voice data for… a long time; and has been running all of that data through a Deep Machine Learning network larger than the world has ever seen, with software that was just recently open sourced as TensorFlow. The AI companion from the movie Her, or the Librarian from the novel Snow Crash, is likely going to be built by Google. Maybe IBM, Microsoft or Facebook will be the one who does it first - however while they are all playing Chess, Google is playing Go. That’s the best way that I can describe it.
In about ten minutes there is an I/O Stream on Machine Learning: Google’s Vision. Maybe check it out. Yesterday one of the sessions was on Machine Learning and Art. One of the CodeLabs is called TensorFlow for Poets. The What’s New with Project Tango session yesterday was mind-blowing and had the head of Google VR, Clay Bavor, come up on stage and participate in a selfie with a dinosaur.
The connection to VR is clear for those who have eyes to see.
