Quite. There's a spectrum from Google Maps (or something worse....Apple? Nokia?) to an electronic Ordnance Survey map. The latter is a reasonable substitute for a paper copy of the same. Sure, you can't lay it out on a table and you have to feed it electrons, but on the other hand it's wind-resistant, readable in the dark, you're not on the edge of the map, it won't wear out from repeated scrolling and doesn't weigh anything (assuming you're carrying the device anyway).
If I'm going off-roading, I'll prefer a paper map (possibly a disposable laser print of the relevant area) because it won't break if I drop it. If I'm touring, I'll use electronic maps on the tablet to save bulk and weight. If I'm on a normal bike ride without such things and have reason to wonder if *that* bridleway works as a shortcut around *this* closed road, I'll peer at a tiny section of OS map on my phone screen, which is what I have with me.
Anyway, paper maps are a reasonable option, at least some of the time. The question is what's a good way to hold them?
