If you want to venture or pivot into RF, especially from software background this is the golden time that's made possible/feasible by software-defined radio (SDR) technology as mentioned in the OP article.
One very important thing that the article did not mention is the emerging and increasing popularity of physical AI [2]. RF can be the crucial enabler to to further enhance human limited sensing capabilities with EM based waveforms. A simple analogy is how the dog's powerful smelling capabilities is helping/enhancing human detection capability.
Rather than just training and inferencing on image based I/O, the physical AI now can feed on the much richer RF, mmWave, THz and LIDAR raw waveforms. The good news is that the latter processing of mmWave, THz and LIDAR, can be greatly enhanced by the former lower RF baseband (modulated information signals) that's not previously possible/feasible.

[2] What is physical AI?
Even as a dot point mentioning the whole WiGig -> IgniteNet thing? Is that not interesting to you?
Just wondering how an LLM replaces that job …
A basic RF design LLM good enough for low end work will kill the development of human talent, leading to an eventual crunch in lack of advanced skills.

It's more business model than skillset, because RF engineering is, in many ways, so much more technically challenging.
People who care about pay should mostly be thinking about how their potential employers make money. Do they have fat variable margins? Is there volume? Do I have the opportunity to impact those margins in some way? If you do, there's a good chance you can make good money, regardless of the actual technical challenge at hand.
For a lot of RF engineering, the answers are generally no, at least enough such that the general market isn't getting set at a high clearing rate.
