I would urge you not to consider this modernization from the perspective you may be familiar, as someone who may work on the bleeding edge and sometimes sees a lack of caution from engineers pushing for change.
The FAAs safety risk management is built around a rigorous process, but that is also a massive slowdown to reasonable progress.
One of the eng I worked with was 80+ years old and just didnt want to retire. He did not understand modern systems at all and the risks we were looking at were not (imo) realistically balanced.
I get the idea that the current administration is pushing safety to the side, but there is another risk where safety becomes a blocker to reasonable change.
When I left that work (more than 15 years ago) it was clearly a blocker.
Magnetic degradation, wear from read/write heads, and environmental sensitivity mean disks have a natural expiration date and it's not long. And they are also easy to corrupt from all kinds of magnetic sources around us.
I get other stuff, even DOS like system. Safety critical software/hardware that was battle tested makes sense. Not floppy. Sometime it's just bureaucracy.
If this is the case, why was an airport knocked offline due to a cut fiber optic? A safety focused system would have a backup system say satellite or mobile 4G/5G. But they didn't have such.
This isn't about safety. Its about bureaucracy wrapped up as safety.
In one role, I worked on writing software for drones.
That very rigorous process was very reassurring to me. Reasonable progress was absolutely occurring.

What kind of risks were you looking at with what kinds of balances, if you're able to share?
If you don't make a change and then there's a plane crash that's not your problem.
Basically when accident rates are already very low, even a small amount of transitional risk can add up to offset years of marginal improvements. So the burden of proof rests heavily on the proposer of change to a system that already is working reliably.
Can you recall anything that that engineer said or did which turned out to be credible? Or which you perhaps learned from?
But this kind of precaution is quite necessary in the development of AI systems. Current regulations have turned a blind eye to accelerate software and AI progress. Now we have security bugs and misalignments, and we will have AI misalignments as well.
Knowing how computing landscape has changed in SV, I can't imagine modern day SV helping fix FAA systems. Alternatively we could go with multiple incarnations of the same system, being battle tested and proven with independent concurrences, alongside current FAA system. Yeah, it is a boatload of money, and probably wasting 90 percent of it in redundancy.
Can you provide any examples you've come across where the current administration has pushed safety to the side with respect to the FAA? I'm curious to read about those. I know there have been some changes to regulations and there are sometimes disagreements around those but I'm not sure if the ones I've seen (which aren't comprehensive) would be considered pushing safety to the side.
we can look at this more holistically than a specific IT project. like in china, which is not a place i want to live, it is still valid to say, their process of steamrolling past local interests means that airport expansion and transit to new airports can be built quickly, which helps meet demand for air travel better than working at the absolute limits of safety and efficiency tradeoffs.
local control in the US infests everything. it causes airports to be too small, guilds to grow too slowly, it opposes infrastructure, it makes politicians too vulnerable and too weak to make changes that upset minor but powerful real estate interests.
so in one POV, safety is a blocker to reasonable change, but everywhere else in the world, they just increase capacity, and the huge stresses on safety limits are reduced.
