Cofounder of The Forecasting Company here - disagree on this. The models now work quite well and are in prod at a number of places, including very sophisticated places - quant funds, top retail cos etc
Do those places also include companies focused on private markets?
You are telling me quant funds prefer a heavy-weight and slow ANN to a fast, specialized model? Maybe in totally non-critical environments, otherwise it's simply too slow, regardless of performance.
