@TansuYegen Physics has nothing to do with „real“. Physics creates mathematical models to provide us the way to calculate answers to our questions. That is all. „Real“ is the realm of philosophy.

We are thrilled to lead Stitch’s Series A, and honored to make this our first investment in Saudi Arabia.

@StitchHQ is building an operating system for modern financial institutions, starting in the Middle East. Its API-first platform enables banks, fintechs, and non-financial institutions to launch, scale, and operate financial products across a modular stack.

In the last six months alone, more than $5 billion has been transacted on the Stitch platform. Customer numbers grew 10x in 2025, revenue grew 20x, and Stitch has seen pull beyond the GCC into Africa and Southeast Asia.

Mohamed, Stitch’s founder, has the rare combination of relationships, sales instinct, and grit to win in a market where trust and distribution matter as much as product.

After years building conviction around the global fintech infrastructure opportunity, we believe Stitch represents the clearest expression we’ve found of what the next generation of this infrastructure looks like.

@elonmusk Or a space station. Running computers on orbit might be even more efficient. Moon still has dust on it.

Germans can no longer sell cars. So, they will build tanks. But tanks last for decades and consumers don't buy them anyway. That's why Military Keynesianism doesn't work, unless you start one war after the other US-style. Ergo, only fools welcome German Military Keynesianism.

[Denis Kalinin @deniskalinin]

@elonmusk It is really good!

[Denis Kalinin @deniskalinin]

@niccruzpatane What about the ticket cost?

@JoeBiden This is so pathetic. The rhetoric of presidential candidates reminds me of drunk people in the bar on Friday night. Watching the greatest country in the world in a such an embarrassing situation is a torture. I am very sorry for it.

@BarackObama How did it happen that no one young and energetic doesn’t want to become a president?

[Lena Petrova @LenaPetrovaOnX]

🚨 Here's a good wake up call for all of us. Are you listening?

U.S. Treasury Secretary Janet Yellen states that "This is not theft. There is no legal issue" in stealing Russian sovereign assets since "the assets generated income for the institution".

Using the same logic, interest income earned on an any investment held at a financial institution, or even a savings account, could be taken from you because the "institution" considers it to be its "income", not yours.

[Denis Kalinin @deniskalinin]

@elonmuskADO No, but alternative is probably worse...
