Nope. I do them seriously. My Mavic 2 Pro has a microSD slot, my Canon EOS 5D Mark IV has a CF slot (it also does have a SD slot too, which is slower and I've never used it).
SD card reader is a nice addition for a handful of pros, sure, but definitely not essential for everyone who does photo/video seriously.
