However, I'm interested in the things Apple doesn't tell you. I would also keep an eye out on the internal SSDs since they cannot be replaced [0] especially if you're continuously using intensive software on it or your Mac keeps having to use a swapfile which degrades the flash even further.

So if you’re writing 30Tb in 2 months, you’ll start hitting the warranted wear limits in 20 months. I don’t think people expect their Apple laptops to fail in < 2 years.
If they’ve gone for (significantly more expensive) 2-bit cell (Samsung 970pro equivalent), then the write limits are 4-5 times greater - Samsung claims 1200Tb for the 970pro. I don’t believe Apple publishes the detailed specifications of their SSD flash chips anywhere though, so it’s impossible to know where the limit is for Apple devices.
The parent tweet is a clear outlier.
