According to internal records viewed by CNBC, employees from Musk's other companies are now authorized to work at Twitter, including more than 50 from Tesla, two from the Boring Company (which is building underground tunnels) and one from Neuralink (which is developing a brain-computer interface).

Talent is the key in tech companies. While it may seems to be a bad move due to he brain drain from Tsla, it goes to show the quality for the engineers that Tsla is able to attract and hire. These engineers enjoy working on complex problems and solving them. It is also a temporary solution given that Elon has sent an ultimatany to the employees. Only those passionate and aligned with his goals will be part of the journey to revamp Twitter.

Here's the full email that Elon Musk sent to Twitter employees on Wednesday (transcribed by CNBC):

Going forward, to build a breakthrough Twitter 2.0 and succeed in an increasingly competitive world, we will need to be extremely hardcore. This will mean working long hours at high intensity. Only exceptional performance will constitute a passing grade.

Twitter will also be much more engineering-driven. Design and product management will still be very important and report to me, but those writing great code will constitute the majority of our team and have the greatest sway.

At its heart, Twitter is a software and servers company, so l think this makes sense.

Anyone who has not done so by 5pm ET tomorrow (Thursday) will receive three months of severance.

Whatever decision you make, thank you for your efforts to make Twitter successful.
