Historically these sorts of things happened because of Moores law. Moores law is dead. For a while we have scaled on the back of "more cores", and process shrink. It looks like we hit the wall again.
We seem to be near the limit of scaling (physics) we're not seeing a lot in clock (some but not enough), and IPC is flat. We are also having power (density) and cooling (air wont cut it any more) issues.
The requirements to run something like claud 4 local aren't going to make it to house hold consumers any time soon. Simply put the very top end of consumer PC's looks like 10 year old server hardware, and very few people are running that because there isn't a need.
The only way we're going to see better models locally is if there is work (research, engineering) put into it. To be blunt that isnt really happening, because Fb/MS/Google are scaling in the only way they know how. Throw money at it to capture and dominate the market, lock out the innovators from your API and then milk the consumer however you can. Smaller, and local is antithetical to this business model.
Hoping for the innovation that gives you a moat, that makes you the next IBM isnt the best way to run a business.
Based on how often Google cancels projects, based on how often the things Zuck swear are "next" face plant (metaverse) one should not have a lot of hope about AI>
So you add your automation crap to HA, scan a QR code from HA and everything pops up in HomeKit
For me that was a bit oof, as it literally adds _everything_. So I just use Apple TV as a HomeKit hub with the basic stuff added directly to it and a few specific devices (Shelly) bridged from HA using a whitelist.
This way the WAF stays high and Siri works properly.
HA still does the more complicated stuff (ATV is on pause -> make lights in the TV are a bit brighter. ATV playing -> dim the lights according to the time of day etc.
For a long time, .NET was completely proprietary, and only ran on Windows.
Now it is open source and cross platform, but it is still fighting the momentum of being seen as Windows-only.
