AI picture generators prefer porn to Middle English, but do read Chaucer?

I tried inputting “Summer is icumin in” (and “Sumer is icumin in”) on an AI picture generator and got the reply: 

“This prompt doesn’t abide by our content standards. Please try again with a different prompt!”

AI is obviously trained in American porn but oblivious to Middle English …

Although, to an extent, it’s relatively keen on Chaucer.

When I suggested:

“Whan that Aprill with his showres soote, The droughte of March hath perced to the roote”…

…it produced the picture below. It must obviously know the language is ‘period’ of some kind and interesting that it has included water.

Just saying!
