PlantNet, iNaturalist’s main competitor in the automatic plant ID published all its observations - 6 million with automatic IDs and 0.6 million verified records.
Thereby, there are 6 million records in GBIF which potentially were not checked by humans at all. Of course, there is a disclaimer in the description of the dataset and it says that only high-confidence data were used.
This is neither good nor bad. Just today’s reality. Hope, iNaturalist won’t do like this.
