We as humans can endlessly produce more data.
Go into the field with your smartphone and start taking photos of flowers, insects, macro shots of grass, walls - thats new data, that never existed before. You go and take the photo of the cloud - thats new data. You go and take the photo of the dirt - thats new data.
You go into the crowd of humans, who all wear different clothes, have different skin color and you take videos of just random people - thats new data. You send a car with Google panoramic camera on the street - thats new data, because buildings could have changed, trees could have changed, lots of things are not the same on the street view after a year.
You can just take photos of your shoes each day and each day your shoe will look differently accumulating dirt or wear&tear and thats data.
You just record a baby mumbling or an old man rambling - thats a new data. You just put an audio recording device in the forest and it records birds singing - thats a new data.
We are not recording and not harnessing a lot of data, a lot of data is just being lost every moment, so i don't fucking see how the data can become scarce or used up. Earth is just a magical place, this planet is full of life and full of data. For comparison the Moon is very empty and there is no data on the Moon, except rooks and craters that almost all look the same.
