I highly doubt that number. Do you have a reliable source for that?
About the only place I’ve seen where rational talk is allowed without getting flame to death is /r/covid19.
Hacker news, unfortunately, appears to have devolved into yet another place full of panic stricken people.
I'm happy to defer to actual stats if you have any.
Page 5 of the recent well-respected Imperial paper on modelling approaches to managing the outbreak has statistics on hospitalisation that I imagine are the current best estimates.

For example, 3.2% of cases aged 30-39 require hospitalisation. Could that rise to 40% after triage? I'm not sure, it seems high, but it depends on what pressures the system is under.
