When I saw the Google demo of a CNN using video to split a single audio stream of two guys talking over each other, I became a believer.

Hey, a small advice for the future: never build your belief entirely on a youtube video of a demo. In fact, never build your belief based on a demo, period.

This is notorious with current technology: you can demonstrate anything. A few years ago Tesla demonstrated a driverless car. And what? Nothing. Absolutely nothing.

I'm willing to believe stuff I can test myself at home. If it works there, it likely actually works (though possibly needs more testing). But demo booths and youtube - never.

Your advice would be a lot more convincing if you had a youtube video of a demo to come with it. Just saying. :P

You can't test most of high end physics at home. I hope that doesn't mean you don't believe it!

A lab publishes an exciting result, what does the physics community do? Wait for replication. Or if you’re LHC, be very careful what you publish.

In theory, there are two separate experiments (ATLAS and CMS) on LHC because of this. In practice, they are probably not independent enough.

It's probably a good idea to ignore high-end physics results for a few years, though.

The BICEP2 fiasco is a good example why.

A rigorous evaluation with particular focus on where it doesn't work would be better.

Do you have a video of this?
