Two different problems: detection, deflection.

Before this, even if we spotted one, we didn’t know if we could prevent impact.

Detection honestly feels like an easier problem, especially as networked sensors and space-lift capacity has improved.

Is there really better confidence we could now detect a similar 2013 Chelyabinsk meteor event?

Yes? Rubin is supposed to contribute, and more broadly we have more and better "eyes" on the night's sky than ever before. There's always the opportunity for more tracking, but tracking without being able to do anything about it would've been pointless.
