[D] Does Deep RL work yet?
Back in February 2018 there a blog article called Deep Reinforcement Learning Doesn’t Work Yet that basically argued that there are almost no cases of Deep RL being used in production systems (as opposed to game or research domains like AlphaGo, OpenAI Five, etc).
Over a year later, has anything changed? Are there any new Deep RL success stories that are in production and making a big impact on business? I would be particularly interested in applications outside of the FAANG companies (although in-FAANG would be interesting too).
