From all their collective apperences, you know that "sustainable growth" and "not demolishing the environment" are not part of Flim and Flam's vocabulary. They are not interested in progress, they are only interested in making a quick buck. They would be, given a sliver of a chance, the ones who would be actually implementing the sort of things the compiuter game industry is getting its colelctive hand slapped over (predatory business practices, lootboxes).
They are NOT entrapenuers and models of ideal business people, nor of inventors, they are confidence tricksters, regardless of what talents they might have that they use to support their con-artistry. Could they be such if they were different people? Yes. And Jubilee could be a fracking monsterous killing machine if she was a different person, but that's not the case is it?
Flim and Flam aren't Richard Arkwright, though; they are closer to Dr. William Whitney Christmas, the guy that designed the
Christmas Bullet, arguably the worst aircraft ever made, who did it basically to get the contract for the money based on nothing more than fancy and blagging (dude essentially smooth-talked his way into a profitable (for him) military commission without any actual credentials - he even told the engineers he kept all the plans in his head when they asked him for them to start working on it). With the exception being that Flim and Flam are marginally better in that they haven't essentially murdered two people yet.
Equestria is
already industrialised, as we have seen both heavy construction gear and hydroelectic dams, a railway system, sewing machines, film projectors, airships, electric lights, fridges, flashlights... In fact a very great deal of stuff that would not be found out of place in, say, Murdoch Mysteries, set at the turn of the 19th to 20th century. Heck, I point out to you that one has to go barely as far back as my parent's generation to when the milkman was still using a horse and cart, before TV and large chunks of Equestrian magic/technology level could easily pass off as into even the 50s in a lot of ways. And we know from Princess Spike that the population of Equestria could easily be well into the tens of millions and could be substantially higher.
I mean, they have a weather FACTORY; factories were not even a thing until the industrial revolution. (And I spent three frag-damn YEARS on the tedium that was the agricultural and industrial revolution, I
know...)
Make no mistake, Equestria is not a medieval or faux-medieval fantasy society; despite the prevalence of magic at the fore, their technology is advanced; not to the digital era, yet, certainly, but WELL into the industrial, maybe last industrial peroid.
Those
seven seconds of the Flim and Flam future show a sky choked with pollution, coming from numerous factories - note how the landscape is not vibrant, but washed-out and muddy? Yeah, this isn't a "yay progress" scene, this is the sort of ecological disaster a Captain Planet villain would love. Rampant industrialisation is not a good thing, as one only has to look at what humasn have managed to do to know that.
