my apologies for my language - i was still referring to GNN in general production use. I do see a lot of cool research coming out ... but i still dont see much in production.

Even alipay uses a plain vanilla word2vec + xgboost for its graph based fraud detection.

Is anyone running anything related to GNN in production ?

this is a critical question because if the tooling isnt available ... all these cool research will actually not go live. And that's what im seeing today.

Not a ding on the researchers...but something to think about.
