But scientifically? Yeah, I'll go with "exciting". The field seemed to move at a tremendous speed, or at least that's how it looked to me as an outsider.
Sequencing within less than a week, extremely rapid movement on the mRNA front (and really, the whole vaccination field - 200 candidates in 9 months), revamped understanding of aerosol transmission, leaps in rapid modelling, tremendous progress in terms of test development, growth in international collaboration, progress in the (public) understanding of chronic diseases, scaling up of wastewater monitoring, ...
Definitely exciting.
