People are answering what you asked but what you probably mean is in a 2d world where two antenna are perfectly in line with the transmitter will the first absorb some of the signal - yes it will, just like two wind turbines in a line it's absorbing the energy from the medium and using it to do work.
It's not always so simple, it might spit some of if out too if it doesn't have anywhere else for it to go and it'll do this in a certain pattern which can, depending on the distance and arrangement ,increase the signal received by the second one. This and similar principles are why you see so many odd shapes for antenna designs such as the many bars on a TV antenna which make it more directional.
Usong your analogy i think Ops question was really if you have a stack of transparent solar panels will the panel below get less power and the answer is of course it will. If one antenna is behind another there will be a small reduction in the power of the signal reaching it, probably very small but with enough of them you could theoretically construct a faraday cage of sorts.
I agree we need ubi or something more dramatic but there's been various decent arguments for how things could work without it.
The most popular is probably a continuation of what happened all through the rest of the industrial revolution. Like how the price of cloth fell when autolooms took peoples jobs, this caused demand to increase and created whole new industries - fashion, fashion blogging, etc, etc. It's easy to think that there's nothing new left but that's because new things are harder to imagine.
There's also a lot of talk about a return to more localized business models, the falling cost of services resulting in smaller communities being able to be self sufficient. The same logic goes on a larger scale also, governments able to offer more complete services at much lower prices reduces the cost of living and avoids the privation and poverty which caused such unrest in previous eras of low employment. Higher standards of living and more opportunities to engage meaningfully with the world or enjoy distractions will result in less political urgency, especially as solutions roll out globally reducing pressures that cause migration, etc.
The doomer model pushed by tabloids and drama merchants just hand waves away everything that doesn't satisfy their urge for bad news, they want us to imagine a world where hyper efficient robots have stolen everyone's jobs but it's 1925, we're suffering after a failed world war and there's no bread... it makes no sense.
We can already see the effects of technology making life cheaper, even this international conversation would have been too expensive for me to participate in fifty years ago. Education resources are actually free now for all but the most obscure subjects, it's hard to think of anything you can't learn free. Entertainment also, creative tools, all sorts of things are available to everyone on the planet - anyone trying to pretend this isn't a huge thing simply isn't being serious.
There's a lot of really complex stuff that goes Into models for how things will unfold and people talk about it all at great length, I feel a lot of people avoid these topics like antivax groups avoid learning about actual science because they don't want things to be complex, they want to feel special and you can only do that when you're certain of your opion because you actively avoided learning any confounding arguments.
Yeah, it's hard talking people out of Andrew tate positions when it's so easy to point to reactionary hate and so hard to find nuanced opinions.
We really need to get to the point we recognize everyone as human and acknowledge that means we're all flawed and biased and needy, and that's OK because that's what life is.
Another union instantly has the same old problems but the left refuses to even consider the possibly of finding a better solution and instead gets mad at anyone who suggests it.
If two identical radios are side by side and tuned to the same frequency, will they both pick up the signal at 100%, or will they wrestle for the same radio waves?
