Politics has made it very likely that we will never know where it started, but that's okay. More important is how the next one could start, which is being investigated more thoroughly now.

If not for the systems put in place because of SARS-CoV-1, SARS-CoV-2 could have spread far more widely before being detected.

Regardless of the politics, it's likely that many labs have reviewed their procedures to be sure people won't be infected by their work/contaminate their work.
