Geoffrey Chaucer wrote The Canterbury Tales between 1387 and 1400. They are collections of 24 stories that runs to over 17,000 lines which are written in Middle English. And it is written in iambic pentameter that is a line of verse with five metrical feet or five sets of unstressed and stressed syllables.
This question is subject to opinion. In my opinion, being ignorant is more costly due to the fact that you may make misinformed decisions which could end up costing you in the long run.
