I still pay most of my bills with checks. I also collect rent and pay rent with checks. Basically my entire financial life except for perhaps eating out and buying useless things online is mediated in cash and checks. This is very normal in my social circle.
Just because you choose to use e-banking doesn't mean that cash and checks are inaccessible, or even particularly inconvenient.
I have a hunch it depends heavily on your location. I have never seen a check in my life, and I have never heard of anyone I know using them. I wouldn't be able to say whether such a thing even exists here. Cash is still a thing but not universally accepted; not having a credit or debit card would be a major inconvenience. Banks can be hard to access because they've reduced offices and opening hours. You don't go there unless you really have to.
Like the sibling commenter, I'm from Finland. The same applies to most of the Nordics though; I doubt my kids will ever see a check. People simply don't use them and cashing one would probably be quite difficult (not to mention expensive).
I don't think there are any businesses here who'd accept a check. Banks would probably do it for a fee, or at least require you deposit the money to your account.
Bills here are paid with bank transfer. It doesn't have to be done though online banking, but doing so is obviously easier.
