Assuming current trends, it will likely be though of as the 21st century's Spanish flu, though that is assuming that the trends continue.
We'll likely think of coronavirus the same way we think of the 2009 pandemic, i.e. it gets a Wikipedia article of its own, an occasional historical mention, but we forget about it when disease is not specifically the topic of conversation.
WHO: 8,000 deaths, 630k laboratory confirmed cases, 43-89 million got sick.

Spanish flu on the other hand killed 3-6% of the world's population!

The CDC estimated 60M cases in the U.S. alone, about 20% of the population:

The WHO gave up tracking cases on July 23, 2009, 3 months after the epidemic started, when it hit several hundred thousand confirmed cases. At that point it just became a part of seasonal flu. It's circulating again this year: in recent weeks it's been the most common seasonal flu variant infecting people, and with 19M flu cases so far this year, there have almost certainly been more deaths from H1N1 than from nCoV.
