It is more like the story is being written as we speak and Monero is the only coin in the top 20 by by market capitalization that has a solution. The question of a market based solution to scalability and the related issue of spam was not part of Bitcoin's initial design. The 1 MB blocksize was added to Bitcoin in 2010 as an anti spam "temporary" fix. Virtually every other coin has copied Bitcoin on this and inherited the problem.

Edit: My take is that the Monero community will likely write the book on the subject.
