This Forbes article titled "There Are 6 'Strongest Materials' On Earth That Are Harder Than Diamonds" has this paragraph:
The quest to make materials harder, stronger, more scratch-resistant, lighter, tougher, etc., is probably never going to end. If humanity can push the frontiers of the materials available to us farther than ever before, the applications for what becomes feasible can only expand. Generations ago, the idea of microelectronics, transistors, or the capacity to manipulate individual atoms was surely exclusive to the realm of science-fiction. Today, they're so common that we take all of them for granted.
In the last sentence, I'd like to use the idiom 'a dime a dozen' instead of 'so common'. But I don't know how to use it. Can I simply replace 'so common' with 'a dime a dozen'? Or do I need 'such' instead?
(1) they're so common that we take all of them for granted
(2) they're a dime a dozen that we take all of them for granted
(3) they're such a dime a dozen that we take all of them for granted
If neither (2) nor (3) works, which I suspect neither doesn't, how can I use this phrase in the sentence?
