Question

What if the 21st century we living in now would have now been just like the stone age?

Answer 1

As I gathered ideas to try and answer this very broad question, I tried to identify a thread connecting the great achievements of “our age.” And since you describe it as the one we’re living in, I’ll assume you aren’t taking a macro view of history. I’ll focus on the 20th century, more of less.
 
This is a basic list of our age-defining achievements, both positive and negative: 
 
POSITIVE
Mathematical & Scientific Advancements
Industrialization
Mass Production
Globalization (economic, giving way to cultural)
Digital Information
Health & Quality of Life Advancements
Space Exploration
Social Advancement
 
NEGATIVE
Environmental Damage
Overpopulation
Genocide
Nuclear Weaponry
Global Resource Inequality
The unrealized negative consequences of our newfound chemical and scientific powers
 
Many of these achievements are interconnected, but to me they all share one trait: We are living in The Age of Power.
 
I think the 20th Century will be remembered in history as the point where we discovered ways to reliably power progress on a massive scale using coal, electricity, natural gas, petroleum, nuclear fusion, wind, solar…and on it goes. Advancement has occurred exponentially across nearly all facets of human life, and it’s all because we figured out how to gather, harness and distribute cheap, abundant fuel.
 
The great challenge moving forward will be finding new sources of fuel to keep us going indefinitely.

Evolutionary Progress
The Consequences — Good and Bad — of Having Paleolithic Bodies in a Post-Paleolithic World

“Though we are not so degenerate but that we might possibly live in a cave or a wigwam or wear skins today, it certainly is better to accept the advantages, though so dearly bought, which the invention and industry of mankind offer.” (Henry David Thoreau, Walden)

Have you ever wanted to abandon it all and seek a simpler life more in tune with your evolutionary legacy? In Walden, Henry David Thoreau describes the two years he spent in a hut in the woods by Walden Pond, detached from mid-19th century American culture, whose growing consumerist and materialist tendencies troubled him. People who never read Walden sometimes mistakenly think that Thoreau spent these years as a hermit. In fact, he was seeking simplicity, self-sufficiency, a greater connection with nature, and only temporary solitude. Thoreau’s hut was a several mile walk from the center of Concord, Massachusetts, which he visited every day or two to gossip and dine with friends, have his clothes laundered, and enjoy some other comforts befitting a well-to-do man of letters. Even so, Walden has become a sort of bible for primitivists who decry the advances of civilization and yearn for a return to the good old days. According to this line of thinking, modern technology has led to the unfair development social classes of “haves” and “have nots,” to widespread alienation and violence, and to an erosion of dignity. Some primitivists want to return the human species to an idealized agrarian way of life, and a few even think that the quality of human existence has been going downhill ever since we ceased to be Paleolithic hunter-gatherers.
