This reminds me very much of Buffer Time from Star Trek: Lower Decks, but applies pretty well to a lot of life. No slack = no margin for error or the unexpected...
And, with publishers, you can get both monopoly _and_ monopsony problems. The latter is, I believe, one reason the attempt to consolidate from Big Five to Big Four failed -- I'm forgetting which two publishers were trying to merge, but angry authors talking about having difficulty selling books, and reduced pay for them, was a key argument.
Yeah... for new stuff, I follow authors I already like on social media and see what they recommend from other folks (and why). I've had a miss or two, but that's generally a good start.
As somebody whose first book came out last month from a (very) small indie press... yeah. In trad publishing, once you've got an agent (not an insignificant step), you only have a handful of shots at the Big Five publishers with your manuscript. If they don't want it? It's small press or self-pub, and good luck getting your book above the sea of mediocrity.
The novel I've got out is urban fantasy, but what I _really_ want to get out there is the hard science fiction series entirely from the aliens' points of view... which is very much not a fit with the current zeitgeist. Because that's unlikely to be a blockbuster, if I ever want to see it in print, I'll probably have to do it myself, with a proportionately diminished chance of finding readers.
(And all this is one reason why writers have day jobs. I'll be pleasantly surprised if my novel income hits even 1% of my tech job salary this year.)
Blood of the Old Kings, by Sung-Il Kim (translated by Anton Hur). Absolutely fabulous fantasy novel -- it's an about folks in an empire literally powered by the dead, and the folks fighting against its worst excesses. Very strange, mythological magic and excellent ethical through-line. This is a reread for me before I dive into the sequel.
You joke, but, alas, there is a _real_ company kinda trying to do this. Reflect Orbital[1] wants to set up space mirrors, so you can have daytime at night for your solar panels! (Various issues, like around light pollution and the fact that looking up at the proposed satellites with binoculars could cause eye damage... don't seem to be on their roadmap.) This is one idea that's going to age badly whether or not they actually launch anything, I suspect.
Battery tech is too boring, but seems more likely to manage long-term effectiveness.
