Interesting thread, with some interesting and divergent beliefs. FWIW, I wrote many checks in the old days. Now, I find them to be a pain, and I'm frugal enough to be annoyed by the cost of postage. Most everything I do now is bia automatic credit card payment. I get a 2% kickback from the card company. I also get an email notification, so I see beforehand if something has gone sky-high. I make one electronic payment each month to the card company. There are some payees that would ding me for a credit card transaction, so they get a bank electronic transfer (ACH). I will succumb to a written check when I'm paying someone unable to handle a credit card or ACH bank transfer. An example is a private purchase from a forum member. I will not send a money order for private purchases; it's akin to sending cash in an envelope. Even if the post office manages to lose one of their own money orders, good luck getting you money back. At least with a check, if it's lost it's unlikely to be drawn on your account.
Now to Onomea's original post, I agree there are likely people who have no clue how to write a check. I offer up an example of a young man at hunter sight in. I asked him to read the range rules and sign at the bottom. He gave his Dad a panicked look. He didn't understand how to sign a form or even what a signature is.
Time does march on. Things change. There are kids who don't know what an LP is; or even a CD. I embrace newness (usually). Life experiences are not static. Heck, I've never cranked a Model T. Am I deficient in some way? I don't believe so.
