I wonder if it would be possible to easily add support for multiple CPUs? It seems to be taking at most 150% CPU, so on my workstation it could be (assuming high parallellism) 10 times as fast.

Alas the word2vec repository has reached its quota:

    fetch: Fetching reference refs/heads/master
    batch response: This repository is over its data quota. Account responsible for LFS bandwidth should purchase more data packs to restore access.
    error: failed to fetch some objects from 'https://github.com/mmihaltz/word2vec-GoogleNews-vectors.git/info/lfs'

So here are another sources I found for it: https://stackoverflow.com/a/43423646

I also found https://huggingface.co/fse/word2vec-google-news-300/tree/mai... but I'm unsure if that's the correct format for this tool. The first source from Google Drive seems to work and there's little chance of being malicious..
