Also, a lot of alternatives are just not there. Rust is not mature; today it doesn't "fully" support SIMD. Go requires a runtime, does not support SIMD, and has a penalty for calling C code.
Looks awesome, wish I had the time to play with it.
I would note however that the use of the AGPL instead of the GPL here is probably legally meaningless. I wrote about this: https://www.devever.net/~hl/agplunenforceable
Even if it were the case, the permissions granted by the AGPL are not mutually exclusive with any other set of permissions. Dual licencing, for example, is a common practice. Thus, I'd argue one can take advantage of provisions of the AGPL permitting modification, but not rely on it, but instead on the provisions of copyright law itself, to actually execute the software. The AGPL is not a contract, it is a copyright licence; as such, the set of actions you can take for an AGPL-licenced piece of software is by definition a strict superset of the set of actions you can take for "all rights reserved" software.
