Yeah, pretty much like that, in Azure and paid openai both let you modify the system prompt also. There is also a creativity (temperature) property that can be modified. When too high, it will hallucinate more, if too low, it will give same output everytime.
Retraining the model costs like hundred million and weeks of computing power.
Smart metering has been a thing in Nordics for past 20 years, and it has enabled per hour pricing that guides electricity usage away from peak hours (you have to build the network/production for the peak consumption, which is a problem).
This is pretty nonsense rambling.
What US of course needs is proper privacy laws. Electricity usage is protected by GDPR in EU, so it would be illegal for anyone else than you and your grid operator to see your consumption.
Fediverse adds level of complexity on it, like you mention.
Malicious Lemmy instance could man-in-the-middle by providing it’s public key in behalf of the user in other side. Normally this can be mitigated by CA, but CA doesn’t fit very well in decentralized system.
You could add AES with users own password, but problem is that same malicious instance could also steal users password.
IMHO false sense of privacy is worst than knowing that stuff is unsecure. Again in my opinion fediverse is comparable to yelling in town square.
They don’t even need to do triangulation nowadays, tower has direction and distance, because the way how 4G/5G work. 5G also has MIMO (meaning one burst of data to you carry data to other clients in same direction).
