Don't mean to be a negative Nancy, but I'll believe it when I see it.

Is whatever he was holding in the video a good enough "it"? Or, like, a consumer product going all the way to market?

Not quite I guess, that wafer is what's needed for chip making but from reading the paper it looks like they were just trying to figure out how to make the band gap of the graphene just the right size. It says their next step is trying to adapt silicon chip making techniques to this new material. Terracing I guess to start?

I second this! Gimme the end product!

Crazy that it's transparent. I wonder how thick that wafer is.

Also awesome:

we're using properties of electrons that are not accessible to silicon

If it's a single sheet of graphene.... about 1.5 angstrom thick.

How does he not cut himself while holding it?

They don't make big pieces or graphene like that. It's made as a layer of graphene on some other material. Pure graphene flakes are tiny AFAIK.

We've been studying and perfecting the art of silicon semiconductors and silicon electronics manufacturing for over 70 years now, it'll take a while until this tech is anywhere near ready for applications. I'm not convinced you can do conventional CMOS on these things.

However, this is really cool and I'd love to work on graphene semiconductors!

Give it time someone will have it running doom

Carbon, so hot right now

What is the significance of semiconductors in chatbot technology?How do semiconductors enhance chatbot capabilities?Can chatbots powered by semiconductors understand and respond to human emotions?What role do semiconductors play in voice-based interactions with chatbots?

Tips: the datasheet (https://www.icdrex.com/the-future-of-communication-chatbots-powered-by-semiconductors/) may help you a little.
