How long will it take to extract a csv of keywords from 40,000 photos in a hierarchy of directories and subdirectories?  THX.

There's really no way to answer that question.  It depends upon your computer. Where the files are located, on a SSD or on a nas.  And they all small 50x50 pixel emoji images or huge 100 meg+ tiff files.  Way too many variables and I doubt anyone has done any time trials on such an operation.

The only thing I could say is that it would probably take less time than it would to copy all those files.
* Did you read FAQ #3 and use the command listed there?
* Please use the Code button for exiftool code/output.
 
* Please include your OS, Exiftool version, and type of file you're processing (MP4, JPG, etc).

Don't use the -csv option with such a large number of files.  Use JSON (-j) or XML (-X) instead.  Read the -csv documentation for details.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
