What conclusion is suggested by detecting three interstellar objects quickly?

The population of interstellar objects may be denser than modeled

The relatively quick succession in detecting three interstellar visitors—'Oumuamua (2017), Borisov (2019), and ATLAS (2019)—points toward two main possibilities regarding our understanding of galactic populations. One significant implication is that the actual density of these objects traversing the galaxy is much higher than what previous theoretical models had predicted. Alternatively, the increase in detections might be attributed to technological advancement, suggesting that current wide-field survey telescopes, such as ATLAS, have achieved the necessary sensitivity threshold required to spot these faint, fast-moving targets with greater frequency than previously possible.
