What I really love about the OED is how it keeps getting better even in its coverage of old words. There are lots of words which ten or twenty years ago had the etymology given us "unknown" but which now have a detailed explanation, thanks to recent research. (If you want an example, I think the word "koala" is one.)
That's simply not true. The OED has the current meanings, in more depth than anyone else.

Also not true. Most books and other texts were written before 2018.
The printed OED does not, though there have been separate print supplements to the print edition that get it closer.
The online edition, OTOH, does.
Tangentially, is there a better use case for moving to a database than 20+ volumes of books? To put it another way, if someone had a database and said, 'hey, let's print this thing out - it will be around 20 large books - and sell it!' ...
