Air trafic controller strikes have plagued our country (France) for many years and I see no indication that it makes our flight safety better
Flight in airports are not safe without air controller. It doesn't make it better, it's a requirement to safety.

AI is entirely deterministic. ChatGPT and StableDiffusion and friends are fed endless amounts of random seeds along with every input to keep them from just saying always the same thing.
The output for a given input (absent random seeds) may be constant, but is the output deterministically correct?
Just to give a little context as a pilot: It is the job of the tower controller to decide who uses the runway when. There are often multiple planes waiting to take off, and multiple planes nearing the airport to land. It's not uncommon for a tower controller to allow a plane to takeoff while another is approaching the runway. The theory is, of course, that the flight will depart in plenty of time. In this case, the c…
Only in the US is it permitted for the controller to clear an aircraft to land while another is using the runway. The rest of of the world does not allow "anticipated clearance".
(Apart from a "land after" clearance where the landing aircraft must accept responsibility for separation.)
Edited to add: how it works everywhere else in the world: the controller is not permitted to clear an aircraft to land unless and until the previous one is confirmed clear. That's why the term is "cleared".

They likely mean { X, Y, Z, T } three spatial dimensions and time which are four orthogonal dimensions. That said, it makes the "moving in" redundant and is shy a few dimensions if you want to go full descriptive phase space diagraming given velocity and acceleration in each spatial dimension are missing.
It is still just changing vectors and speed in three dimensional space so...
A Four-Dimensional Space-Time Automatic Obstacle Avoidance Trajectory Planning Method for Multi-UAV Cooperative Formation Flight
or any number of other similar papers.
Many prefer to think of an objects path as a trajectory in space-time (four dmensions) and for two ojects to "collide" their paths must coincide within that 4-D space within an Epsilon for some value of WTF.
Other common examples of working in N dimensional spaces for values of N bigger than someones mother include: https://en.wikipedia.org/wiki/Phase_space

No, no and no. Safety critical systems must be validated to be safe in the operational domain and for that they must be deterministic. AI is anything but that.

I'm not sure how many people know this, but one of the first instances of "union busting" ever committed by the US federal govt was against air traffic controllers. The job used to be extremely competitive and prestigious, but overall lower wages and security has made it way harder to attract as many highly talented individuals. And with how many rules there are in that pdf, it's shocking we don't see multiple accide…
I don't knock unions but I will add : > The median annual wage for air traffic controllers was $129,750 in May 2021 SOME unions do take advantage, given the traffic controllers' 'single point of failure' it can be very attractive for some unions who are greedy. Again I reiterate, unions are not a bad idea, just not all of them are solely in the interests of the actual employees.

"Deterministic" only insofar as it's repeatable, but their behaviour is not predictable. If the behaviour is not predictable, how can it be validated as being correct?
I'm not sure what you mean with "is not predictable" when you also admit that it's repeatable.

I personally think stability and having some bureaucrat monitoring hours is good. I don't want my air traffic controllers popping pills and pulling double shifts, or showing up to work drunk because they're worried about getting fired for calling in sick. People with dangerous jobs need to be kept safe from themselves
Much like air hosts and pilots, air traffic controllers (at least in the EU) are tested frequently for substance issues including alcohol. A friends father who was an air traffic controller was tested daily for the very reason you mention. Nobody WANTS an accident.

Absolutely agree, they're professionals though and well trained. I believe they can be responsible adults. That's why it's so rare to see unfortunate mistakes like this seems to be.
