It is very possible that Trump and his cronies are just too incompetent to do that. In this one particular aspect (i.e. open source) I prefer having a stupid enemy than a "smart" enemy.
I still like System76. I know the Cosmic rollout was rough, but I still see potential. Open Source systems have often struggled to compete with proprietary systems in many areas. Often it comes down to the lack of a viable business model. System76 has a viable business model: sell a complete turn key Linux system that Just Works. I hope they pull it off.
To give credit where credit is due, it is good that the Trump administration has not avidly played these stupid export control games. They tend to do little except hurt open collaboration; I remember when all open source cryptography had to be developed outside the US due to ITAR.
However the second part of that aphorism is "but some are useful". I have often wondered how much of IT/Programming is just sticking well understood pieces together. I remember 8 years ago wondering why we could not replace LLVM with a much simpler system that replaced all the manual optimization with a simple AI "optimizer" trained to transform simple compiled code into "optimized" code. I remember the consensus being that the AI system could likely not produce correct code reliably enough to be used. If AI cannot replace such "low level" code, then surely "high level" problems are widely out of reach. Yet people use it for "high level" problems. What gives? My hypothesis is that a lot of modern digital engineering is "plug and play".
I read the article, and it seems she is forgetting the aphorism "all models are wrong". This is a common mistake that people who like "realistic" "simulation" RPGs often make. Any suitably comprehensive model of a thing is just the thing itself. To have a model of a location that includes all the detail of the actual location, you would need a 1:1 scale model, which is just a copy of the location.
Any plan (i.e. prompt to a model) sufficiently capable of reliably replicating 100% of the functionality of a system is likely the source code of the system itself.
In my Traveller RPG campaign, which is set over 3500+ years in the future, Star Citizen is still not out yet. The joke is that the space opera future has arrived before Star Citizen. It has been in omega for the past 1000 years since they ran out of Greek letters.
I saw a Waymo for the first time IRL last week in Atlanta. It stopped on a narrow street for about 5 minutes to wait for the person to come out. The people in the cars behind it were not happy!
