Maybe. But a possible contributor for the 1918 flu pandemic's relative obscurity is that it overlapped with World War I and was followed within ~20 years by the Great Depression and World War II. It occurred during one of the most turbulent times in modern history.

In contrast, the 2020 pandemic is presently not sharing the spotlight. Maybe something of comparable impact will happen. Or maybe it'll be forgotten regardless. But I don't know that the 1918 pandemic's status is all that illustrative.
