Someone (not me, I'm busy) make a new Twitter and call it Bitter. It's gonna make GAJILLIONS.
Someone has to say it: Elon Musk has lied for 27 years about his credentials. He does not have a BS in Physics, or any technical field. Did not get into a PhD program. Dropped out in 1995 & was illegal. Later, investors quietly arranged a diploma - but not in science. 🧵1/
A buddy who's interested in end-to-end encryption (E2EE) but hasn't done one of these projects in the very messy place which is the real world happened to ask me this morning about pitfalls which might not be obvious. So here's a partial list in the hopes that it's helpful. 🧵
One of the things that I think is sad about the decimation of Twitter eng is that Twitter was doing a lot of interesting (and high ROI) engineering work that, at younger companies, is mostly outsourced to "the cloud" or open source projects A few examples off the top of my head:

Ok refreshing the home timeline on the Android Twitter client makes a total of 3 HTTP requests. The first two of these are in parallel, the third occurs after the response from the second (it's the query for avatars). Total time: 1.519 seconds.
Mr Musk, uninformed all around, Helmed Twitter & ran it aground. The tweeting however Was better than ever For daily this man was beclowned
The Basque language has always been surrounded by mystery with regards to its origin. Today, there has been a massive breakthrough on its history and origin 🧵
It took me less than 25 minutes to set up a fake anonymous Apple ID using a VPN and disposable email, attach a masked debit card to it (with the address being Twitter's HQ), and get a verified account for a prominent figure. Just think what a nation-state or bad actor could do...
I feel these anniversaries are occurring at an accelerated rate and I don’t like it.

Are we sure this is not the Twitter Musk merger agreement?
Imagine making this detached starving blockchain-obsessed Rasputin-looking quisling look like the competent bird CEO.
Leadership has asked your team to treat half the company as a potential insider threat.
