I have to admit this draws attention to yet another question about the Burn.So... There are handheld devices that can create portals between planets?
Wow... Where were those things during the 120 years of galaxy wide darkness...
Whenever people gripe about the interstellar beaming in the Kelvin movies I point out that by the end of Voyager they'd established loads of ways of doing this, and while some of them are risky, it would be a little weird if they didn't keep advancing and using those. (Though the beaming in the Abrams movies seemed to have a subtext of being too dangerous to do under normal circumstances too IMO, even if it wasn't stated explicitly.)
So with subspace transporters ("Bloodlines"), interstellar Dominion transporters ("The Jem'Hadar", "Covenant"), spatial trajectors ("Prime Factors"*, "The Impossible Box"), Iconian gateways ("Contagion", "To the Death"), transwarp beaming (the movies), time travel tech that let you change physical locations as well ("Relativity", "Shockwave", "Azati Prime", etc.), and probably others I'm forgetting in addition to this episode, it feels like there should still have been loads of interstellar transport.
Maybe it wouldn't have been as practical for moving large quantities of resources between systems, but it's something.
Not a gripe about this episode at least; if anything, it means I barely blinked when they added another way of doing the same thing.
* Originally required a very specific type of planet, though this may have been retconned.
