> Trusted Execution Environments (TEEs) like Intel SGX and AMD SEV-SNP and in general hardware attestation are just f*d. All their keys and roots are not PQ and I heard of no progress in rolling out PQ ones, which at hardware speeds means we are forced to accept they might not make it, and can’t be relied upon.

one thing I liked about cobra is the auto complete support, but I don't like the manual process of define command and parameter and not easy to extend, so I wrote https://github.com/hujun-open/myflags, it is built-on top of cobra but allow uses a struct to define all commands/args and also easily to extend support new types (even existing types)

quote from tiktok's webiste https://usds.tiktok.com/usds-myths-vs-facts/:
```
Myth: TikTok’s parent company, ByteDance Ltd., is Chinese owned.
Fact: TikTok’s parent company ByteDance Ltd. was founded by Chinese entrepreneurs, but today, roughly sixty percent of the company is beneficially owned by global institutional investors such as Carlyle Group, General Atlantic, and Susquehanna International Group. An additional twenty percent of the company is owned by ByteDance employees around the world, including nearly seven thousand Americans. The remaining twenty percent is owned by the company’s founder, who is a private individual and is not part of any state or government entity. ```
