A new generation of neutrino experiments is testing the $4.7sigma$ anomalous
excess of electron-like events observed in MiniBooNE. This is of huge
importance for particle physics, astrophysics, and cosmology, not only because
of the potential discovery of physics beyond the Standard Model, but also
because the lessons we will learn about neutrino-nucleus interactions will be
crucial for the worldwide neutrino program. MicroBooNE has recently released
results that appear to disfavor several explanations of the MiniBooNE anomaly.
Here, we show quantitatively that MicroBooNE results, while a promising start,
unquestionably do not probe the full parameter space of sterile neutrino models
hinted at by MiniBooNE and other data, nor do they probe the $nu_e$
interpretation of the MiniBooNE excess in a model-independent way.
