True, however, people have been very creative in finding ways to make sous vide work for things you wouldn't normally think they'd be effective at.
For example, I came home from work around midnight last night & threw some bacon on my skillet (the leftovers from the first batch sous-vide & threw in the fridge). It took a couple extra minutes to heat up (since they were cold), but it was so nice having bacon FAST & having it come out really good. Also, the texture (softness & slight chewiness) reminds me of good restaurant bacon, so I'm pretty happy with how it turned out & will probably sous-vide up a few separate packages of it to keep in the fridge & freezer to use on a regular basis.
Also, I picked up an extra tool for my kitchen arsenal - an 1,800-watt portable induction burner. It goes up to 575F in 5F increments & goes for $110 shipped from Amazon. I was able to get my Teflon pan up to over 400F in literally under a minute (also tested my non-stick metal pan, which took about 3x as long, but was still a LOT faster than my flat-top electric non-induction stove). I typically only cook with one burner (my go-to devices are a combination of the Anova, Instant Pot, and toaster oven) & also cook outdoors (grilling), so it's awfully nice to have a really powerful single burner available that I can just plug in wherever I'm at.

The cooking technology available these days is just incredible; it's also awesome that it doesn't cost an arm & a leg like it used to.
