Uber Technologies has reported strong earnings for Q2, with revenue increasing by 16% year-over-year. This performance is seen as a positive indicator of economic strength, although some analysts suggest it might mask underlying economic weaknesses, as the gig economy plays a significant role in these figures. The number of Uber drivers has increased by 20%, highlighting the growing reliance on gig work. Uber's earnings stand out amid a generally gloomy technology earnings season, with the gig economy emerging as a bright spot.
