Is the point of this privacy, offline analytics, or eliminating server costs, and does that survive the download cost of 95 megabytes?

They have compiled to WASM64, the newer 64bit version of WASM. That's not available on iOS yet.

WASM till recently has had a 32bit address space, to match the limitations of JS numbers. With 64bit WASM you have to use BigInt rather than the floats that are numbers in js to address the memory.

It's only the address space that's affected - old WASM still handled 64bit math fine.

I like the initiative but would love if there was a heavily stripped down version, it seems this one needs to download 95mb+. DuckDB also has a WASM version which is also not tiny but comes in at something like 36mb if I recall correctly.
