Look at your phone. It’s a slab of glass and silicon that can tap into the collective knowledge of every human who has ever lived. We’ve split the atom. We’ve landed rovers on Mars that send back high-definition selfies of red dust. From the perspective of a Victorian-era chimney sweep, we are basically gods. But in the eyes of the universe? We're barely a blip.
Honestly, if you're asking what type of civilization are we, the answer is a bit of a reality check. On the scale that actually matters—the Kardashev Scale—we haven't even made it to the first rung of the ladder.
We are a Type 0.
That sounds harsh. It feels like getting a zero on a test you studied really hard for. But the metric isn't based on how many followers we have on TikTok or how fast our 5G speeds are. It's about energy. Specifically, how much of our planet's power we can actually harness and control.
The Kardashev Scale: The Cosmic Yardstick
Back in 1964, a Soviet astronomer named Nikolai Kardashev was looking for signals from extraterrestrial life. He realized that any advanced civilization would need massive amounts of energy to transmit signals across the void of space. So, he built a ranking system based on energy consumption.
The original scale had three levels. Type I can use all the energy available on its home planet. Type II can harness the total energy output of its parent star. Type III? That's the big one. A Type III civilization controls the energy of its entire galaxy.
Carl Sagan, who was never one to settle for simple integers, later refined this. He did some math and suggested that we weren't a 1, but we weren't a total zero either. In 1973, he calculated that humanity was roughly a 0.7.
Think about that.
We’ve had the Industrial Revolution, the Digital Age, and the AI boom, and we’ve only crept up to about a 0.73 or 0.75 in the decades since Sagan’s estimate. We are still deeply dependent on dead plants—fossil fuels—to keep the lights on. A true Type I civilization doesn't just use energy; it masters it. We're talking about controlling the weather, preventing earthquakes, and capturing every single photon of sunlight that hits the Earth. We aren't even close to that level of mastery.
Why We Are Still Stuck at Type 0
The transition from Type 0 to Type I is arguably the most dangerous period for any species. It’s what some futurists call "The Great Filter."
To reach Type I status, we need to generate roughly $10^{16}$ Watts of power. Right now, we get most of our energy by burning things. That’s a very "Type 0" move. It’s messy, it’s inefficient, and it creates a massive amount of waste that threatens the stability of our biosphere.
Michio Kaku, a theoretical physicist who talks about this often, points out the irony: the very technologies that could propel us to Type I—nuclear power, biotechnology, artificial intelligence—are the same ones that could wipe us out before we get there. We have "God-like technology" but "Paleolithic emotions." That's a dangerous combo.
If you look at our current global situation, it’s a mess of Type 0 behavior. We have global telecommunications (Type I), but we have nationalistic borders and sectarian conflicts (Type 0). We have a global economy, but we lack a unified way to manage the planet's resources. We are a "Type I" birth happening in real-time, and it is a painful, bloody process.
The Energy Gap
To understand the gap, consider the Dyson Sphere. This is the hallmark of a Type II civilization. Named after Freeman Dyson, this hypothetical megastructure would completely surround a star to capture its entire energy output.
We can't even build a reliable high-speed rail across most countries. The jump from building a bridge to building a shell around the Sun is... significant.
If we ever want to move past what type of civilization are we right now, we have to solve the energy problem. Fusion is the most likely candidate. If we can master "star power" on Earth—creating more energy from a reaction than it takes to start it—we leapfrog toward Type I. Until then, we’re just kids playing with matches in a house made of cardboard.
The Risks of Moving Up the Scale
It's tempting to think that becoming a Type I or Type II civilization is all upside. More energy equals more progress, right? Not necessarily.
Every time we increase our energy consumption, we increase the heat signature of our planet. This is basic thermodynamics. Even if we had 100% clean energy, if we used enough of it, we’d eventually cook ourselves just from the waste heat of our machines.
Then there’s the issue of centralization. A Type II civilization might need to strip-mine entire planets to build a Dyson Sphere. Is a civilization still "advanced" if it destroys its neighboring worlds to power a giant computer or a faster-than-light engine?
We also have to consider the "Singularity." As we move toward Type I, the role of biological humans might diminish. We’re already seeing the beginning of this with neural interfaces and AI. A Type I civilization might not be made of flesh and bone at all. It might be a digital collective. That’s a weird thought. It changes the definition of "we."
Beyond Kardashev: The Barrow Scale
Some people think the Kardashev scale is too focused on "big" things. John Barrow, a cosmologist, proposed an alternative: the Microdimensional Scale.
Instead of looking at how much energy a civilization uses, Barrow looked at how small they could go.
- Type I-minus can manipulate objects they can see (building houses).
- Type II-minus can manipulate genes and molecules (modern medicine).
- Type III-minus can manipulate atoms (nanotechnology).
- Type Omega-minus can manipulate the structure of space and time itself.
Under this scale, we’re actually doing much better. We are firmly in the Type II-minus / Type III-minus range. We can edit DNA with CRISPR. We can build transistors so small that quantum tunneling becomes a problem. Maybe our destiny isn't to build giant spheres around stars, but to become so efficient at a microscopic level that we don't need that much energy in the first place.
The Timeline to Type I
So, when do we actually level up?
Most physicists, including Kaku, suggest that if we don't blow ourselves up or trigger a total ecological collapse, we could reach Type I status in about 100 to 200 years.
That’s not that long.
Your great-great-grandchildren might live in a world where the term "energy crisis" is a historical curiosity. They might live on a planet where the climate is managed by a global thermostat and where the distinction between "online" and "offline" doesn't exist.
To get there, we have to navigate the next century without a total systemic failure. It requires a shift from "me-centric" thinking to "species-centric" thinking. We need to stop acting like a collection of warring tribes and start acting like a planetary collective.
Actionable Steps for a Type 0 Species
It’s easy to feel small when talking about galactic civilizations, but the transition starts with the choices we make today. We are the architects of the bridge to Type I.

- Support Fusion and Next-Gen Energy: The path out of Type 0 is paved with energy density. Support policies and companies working on nuclear fusion and advanced geothermal energy. Solar is great, but we need something that can provide baseline power at a planetary scale.
- Think Globally, Act Planetarily: We need to move toward global cooperation on issues like satellite debris, oceanic health, and atmospheric regulation. These are Type I responsibilities.
- Invest in Resilience: A Type I civilization can survive a Carrington Event (a massive solar storm) or an asteroid impact. We currently can't. Supporting space situational awareness and planetary defense isn't sci-fi; it's existential insurance.
- Master the Micro: Since we're doing better on the Barrow Scale, lean into it. Support the development of nanotechnology and room-temperature superconductors. Efficiency is just as important as raw power.
We are currently in the most exciting, terrifying, and pivotal moment in human history. We are the generation that gets to decide if we stay a Type 0 footnote or if we finally become a true planetary civilization. The choice is literally in our hands, and the clock is ticking. Overcoming the "Great Filter" isn't guaranteed, but it's the only way forward if we want to see what's actually out there in the stars.
