New comment by riv991 in "The SpaceX IPO will be the theft of the century"

riv991 — Thu, 04 Jun 2026 06:13:36 +0000

I liked Matt Levine's take in his latest podcast. You buy an index because you want to own the market. If you want to own the market in 2026 you want to own SpaceX and Anthropic, and probably OpenAI too.

That said, if you think this is as bad as the article claims you'll obviously buy SpaceX at IPO, then sell it when Index funds are obligated to buy.

High Scale is so subjective here, I'd hazard a guess that 99% of businesses are not at the scale where they need to worry about scaling larger than a single Postgres or MySQL instance can handle.

> So it is in a bad state because it does not receive enough money, that's it

In real terms the budget is the largest it's ever been, it's a relic of the time when people worked and died shortly (a decade) after retiring, not when they live for 30+ years longer.

It's much easier to maintain, as headsets have become integrated it's become harder and harder to work with anything that runs from the brake levers through the frame.

Microsoft were very quick to highlight their extensions being safer after this.

Isn't that the most impressive part? That the abstraction makes it seem so simple

In S3 simplicity is table stakes

Something really similar happened to me, I broke my radial head cycling last year.

2 days later I got a call from the doctor telling me to start moving it as much as I could, I asked when I should stop with the sling and he told me yesterday.
