The development of mankind is not an accelerated development, but an accelerated development. The development achievements made in the past 100 years are equivalent to the sum of previous histories. The Soviet astronomer Nikolai Kardashev proposed a way to classify cosmic civilizations into three types or three classes according to the energy and control technology available to them. According to his method of division, humanity was at 0Level 73 civilization, now.
Yes 0Level 75, the first level of civilization has not yet been reached. Having reached the first level of civilization, human beings can fully use the earth's resources.
As a Soviet, Kardashev should know that the difficulty of entering the earth is much higher than that of going to the sky and entering the earth, which will directly affect the exploration and utilization of energy, and the record of the deepest length of human excavation is 1226 km, or they Soviets themselves created. Therefore, there is a bug in his division of civilizations, which is equivalent to setting the difficulty of the first level in the game to be higher than the second level. In the future, humanity will bypass the efforts to fully utilize the earth's energy and jump directly to the second level. At least that's what Musk thinks and does at the moment.
On December 28, 2023, the Parker Solar Probe completed its 18th flight close to the sun, setting a new distance and speed record, and taking an important step for mankind to explore the mysteries of the sun.
