Yes, but early. I changed my mind from thinking it was "just the flu - I'm going to get it, but probably won't be able to tell it apart from a cold" to "this is probably a big deal that I really don't want to get" in late February. Haven't found any information to make me change my mind since, even as public opinion has yo-yo'd.
The critical information for me was data on hospitalization rates, along with some math on hospital capacity and exponential infection rates. Before, I'd looked at the death rate for 20-40 year olds of ~0.1% and figured it wasn't a big problem for me. Then I realized that the 20% "severe" cases out of Wuhan was actually the percentage that required hospitalization, not just the percentage that develop pneumonia (which is ~60% of symptomatic cases, ~30% of infections). And it doesn't vary by age range nearly as much as the death rate does: while only about 0.1% of 20-40 year olds die from COVID-19, 3-5% end up in the hospital, only about 4x lower than the ~20% of 65+ seniors that do. (These numbers already account for asymptomatic infections, which are about 50% of cases. The Wuhan numbers didn't, so halve them.) And the average hospital stay lasts for 3-5 weeks. With the doubling time of unchecked COVID-19, we could potentially end up with 150M infections during the time period of one hospitalization. 10% hospitalization rate over the whole population, and that's 15M hospitalizations, well over the number of hospital beds in the U.S.
If you gather data from a wide variety of sources instead of grabbing the latest headline, most of the relevant data hasn't actually changed all that much since February. Back then we were saying a roughly 2% CFR; now best estimates are a 1-1.25% IFR, which is completely consistent with that when you add the new information that 50% of infections are asymptomatic, which was discovered in late February. IFRs in situations where the whole population was tested (eg. South Korea, the Diamond Princess) were about 0.7-1.5%, depending on the age of the population. The age curve data from Wuhan has held up remarkably well across Europe and NYC. R0 and doubling time was pretty consistent across most temperate northern climates before the lockdowns (1.5-2.5 days in most of Europe and the U.S.). The progression of the virus when unchecked was also quite consistent between Wuhan, Italy, and NYC, as was the effect of the lockdown.
