That's the joke. Nearly every proposed implementation of AI isn't actually solving a real business or tech problem. It's just the next snake oil, like block chain, quantum computing, etc. There are real, valid use cases for all of those things. But most companies have no idea what they really are, how they might help, and even if they could help, what it would take to implement to see real results.

It reminds me of how tech companies are all scrambling to use AI. There was a funny article recently where the author pointed out that these companies are struggling to do very basic things, so the idea that they could somehow tackle AI in a way that's useful and profitable is silly.

Here's the article, very entertaining and worth the read.

Cool. Now can the local power companies (in cahoots with CPUC) stop changing the rules that make it less and less economically viable for people to have solar on our roofs? Every year they add bigger fees and pay tinier amounts for power generation. The ROI on solar is now measured in decades. And they're doing it on purpose.

Just imagine the average reddit, twitter, facebook, and instagram content. Then realize that half of that content is dumber than that. That's half of what these AI models use to learn. The "smarter" half is probably filled with sarcasm, inside jokes, and other types of innuendo that the AI at this stage has no chance of understanding correctly.

I have this exact model, and I wish I didn't. It turns out there's a flaw in the logic that controls the heating elements. When in "Energy Saver" mode (the default mode), the lower heating element won't heat the water. So when you start to use the hot water, as the hot water goes out, the replacement cold water coming in isn't getting heated at the bottom. This drops the temperature of the existing hot water in the tank, and it takes several hours of no hot water use for the tank to get to your desired temp. For my family it means we get about 1 1/2 showers (showers last about 7 or 8 minutes) before the water starts coming out lukewarm. You can see this happening on your unit by activating the diagnostic mode on the panel and watching the lower element water temp.

I went several rounds with Rheem's customer support (including have two separate techs come to my house to inspect it) before someone finally acknowledged in writing that there's a known defect in the logic of the controller board. They tagged my unit as defective, but so far have not been able to replace it since they haven't engineered a fix and started producing a new version of the water heater with said fix.

My advice, stay away from Rheem hybrid water heaters for a while until they get it sorted out. Also, pro tip: Keep it on the "High Demand" mode so that it's always using electricity + heat pump to heat the water. That gives you the most aggressive heating profile and does not contain the flaw where the lower heater element won't activate. This was the advice their engineer gave me, and it's allowed us to have hot water for more than a shower or two.
