Kardashev's level-1 civ is another Planetary Civilization. I forgot to mention in the 0-level post that there are three types of civilizations, the first being planetary, meaning that it's energy-producing capability and power is limited to the planet whereon it is employed, and upon other planets in our solar system. We have, to date, landed people on the Moon, but the Moon is not another planet in our solar system, so it doesn't count for advancement We have successfully sent mechanical "robots" to Mars and other planets, and operate them from Earth, but all those are within the Solar System, so they don't count as advanced civilization, either. One must advance beyond type 2, engaging in type 3 civilization to advance beyond planetary civilization.
The second type is Stellar Civilization, wherein the energy sources are capable of powering other star systems within our galaxy, up to the powering of all star systems within the Milky Way, encompassing type 4 civilization.
The third type is Galactic Civilization, wherein the energy sources are capable of powering other galactic systems, up to the powering of the entire universe. We have a long way to go, since this is only achievable in type 6 civilizations.
So, back to planetary level-1 civ: Kardashev calculated that a level-1 civ was 200 - 500 years ahead of us; "us" being within the decade of our first landing and walking on. the moon, nearly sixty years ago. We had computer tech in its infancy; no independent hand-held devices, yet.
W'hat tech we hold in our hand, now, required room-size computing systems in the 60s, and much of that reduction can be attributed to the miniaturization required to leave Earth in a capsule capable of maintaining our lives in a relative vacuum in space immediately around the Earth. So, next time you think our investment in space exploration would be better served here on Earth, remember to toss your smartphone in to the trash, because you would not have it without space exploration. Consider that our tech, today, cannot match the concrete developed by the ancient Romans, and at that, our ancestors lost the formula and we re-invented a less capable version just 200 years ago, and have yet to match the Roman version.
