* Knockoff (and even some really really crappy real steel) red dots are difficult to see in bright sunlight.
* Knockoff (and again, crappy real steel) red dots cannot be turned low enough at night, that they do not practically obscure everything in the FOV of the optic, by shining its bright light into your darkness-adjusted eye.
* When the batteries die, or the optic is damaged, then the optic is useless.
* They add a fair bit of weight and additional potential snag points to the rifle.
With the way I handle my firearm, a good optic adds way more value than it takes away with these (potential) draw backs. I can understand the appeal of sticking with irons, and I do just run irons from time to time. But a good optic is generally an asset.

Those are good points, and you're right just like everything, there are good and bad to everything. But for the most parts, a good scope outweighs irons. Irons should really be left as a backup, which is how most people have it set up.
For rifles like the carbine, the ideal setup is to have a scope and then flip up backup irons to take its place if the battery runs out or if it malfunctions or gets damaged. With say the magpul ones, they spring load, so its as easy as pressing a button and you're good to go.
With hand guns, say on a glock, you can use the trijicon RMRs. Same thing. If batteries run out or it gets damaged, then you simply go to the existing iron sights on the glock.
In this modern age, the red dot type scopes (or holoscopes) are really the only way to go because its so much easier to acquire targets. Even targets at a range, I don't buy the large MOA dot argument as the reason to stick with irons. With irons, your field of view is way worse because you essentially the irons block off a lot of the view and they themselves are actually quite big, equivalent to a big dot in terms of covering the target.
