He did it and he's taking the company private.

A lot of financing. He needs $21 billion in cash, which may explain why he sold $8.5 billion worth of Tesla stock in the past few days - reducing his ownership from 17% to 16%. 

What's next?
Twitter shareholders will get to vote to approve the deal.

What are his ideas?
He wants to get rid of the spam on the platform. He also wants to authenticate all humans - which I think is a great idea. If you've proven you're a real person, you'll get a badge which I assume will be similar to the blue tick. He wants to open source the algorithm to build trust through transparency.

But will it happen?
If Elon decides to walk away, or can't secure the financing (especially after the Tesla stock price dipped) he'll have to pay $1 billion to Twitter, but Twitter could walk away from Elon for $1 billion if it gets a better deal from someone else.

Snap's drone

Pixy is a drone dedicated to taking photos of you while you're out and about doing fun / cool things. It will fly for up to 20 seconds to get the video, and can do that five to eight times on a single battery. You'll be able to purchase extra batteries. It's certainly not for hardcore videographers but more of a toy. But it's an expensive toy at $230. Currently it's only available in the US & France.
