I don't understand the glee about deepseek being open source.
How many people are running Linux right now, on the desktop or phone they are using to read this?
How many people use something other than Google, Siri, or Alexa for search?
How many people are on Mastadon for social media?
The internet is inherently organized around brands, not traditional moats. We all happily use products which psychologically manipulate us to our detriment, which spy on us - even listening to our ambient conversations to identify what we're talking about and geolocating us, which give "sponsored" answers to questions and searches, and which overall deliver a mediocre experience because it's the default of what everyone else is doing. Convenience and the illusion of being "free" seem to be all that matters.
WRT the fantasy of running open source AI on your own device I have to ask how many petabytes of data will you be storing on your home server farm? Who will sell you these data? How much will the processors cost (H800s start at about a grand apiece) and how many hundreds of them will you have? How will you handle the five-figure monthly electric bill to keep all this running? Will your server farm be in an outbuilding, and is the nitrogen fire suppressant system up to code?
One might appeal to the old Moore's Law here and say just give it time and our server farms will become a laptop, but then why are we all still searching with Google over 20 years later, instead of running our own open source tools? Why are >99% of us defaulting to MacOS or Windows, which is increasingly adware, rather than wiping our new computers and installing Linux? Hell, that last move is 100% free and requires minimal technical skill, and yet we won't do it. And this is not even addressing the observation made years ago that Moore's law is breaking down, and will continue to flatline absent some advance like quantum computing. A thousand H800s may never fit into a laptop, for the same reason our airliners don't fly Mach 5 in the year 2025 and for the same reason atomic car engines never worked out. They'll eventually hit an engineering limit.
Even open source tools will eventually be packaged in a convenient app with a brand and ad campaign, preinstalled on new devices, and all the other monopolistic tricks that governments allow in the internet economy. MacOS is, after all, derived from Unix, which tax dollars paid to create. At this point, and after so many consumers have had the opportunity to embrace open source and failed to do so, I cannot imagine something as complex as an AI being the thing we decide to try first.
