Think carefully and be afraid! What has happened to mankind in the past 200 years? What a change!

Humans first lit bonfires, and now they use internal combustion engines.

A torch, a powerful racing engine, although the technology behind it is 10 thousand times more complicated, there is no progress in the way of energy utilization, and energy is obtained through chemical combustion. A bonfire is to light branches directly, using light and heat.

The internal combustion engine is ignited by mixing fossil fuel with air, producing high-temperature and high-pressure gas, which drives the piston to do mechanical movement.

Under the exquisite technical shell, the core of the package is still a simple and ancient thing: lighting a fire.

In terms of core technology, battery cars are more innovative than Mercedes-Benz.

Therefore, when I ride a small battery car past the Mercedes-Benz 4S store, I will have a sense of superiority with leading technology.

It's exciting to see the launch vehicle go into space. Do you admire human greatness?

In fact, it's just the ultimate monkey. I am by no means belittling the value of astronauts. Compared with scientists, we are like primitive apes who occasionally throw a stone.

After mastering certain skills, the skilled workers in the firecracker factory surpassed the original ape, wrapped black powder in paper and added a bamboo stick to make a monkey flying high.

After mastering more technology, the engineers of the military factory developed anti-aircraft guns. They can also fire shells with radio proximity fuses and beat the ash machine. This is an advanced monkey that fireworks workers can't reach.

After mastering more and more technologies, super humans were born: astronauts. They made a super monkey: a chemical rocket, and then sent a Soviet satellite, heroes yury alekseyevich gagarin and Yang Liwei into space. Maybe even send a bunch of nuclear warheads to lighthouse countries.

At this time, soil apes, fireworks factory workers and military factory engineers all looked at it as if they were watching a miracle.

However, under all these technological advances, the core technology of the package is still: burning flames (except for the earth apes throwing stones)

Burn what? Burning black powder, burning shell propellant, burning oxidant and fuel ellipsis …

All of us will not see real and core technological progress in our lifetime.

Human life is too short. Most people born on this earth don't know that the earth is round at the end of their lives, and they still revolve around the sun. People in the future will look at us as we look at these ancestors.

As mentioned earlier, protozoans carry cement and bricks.

So what technology is this?

The sun is like a super fusion furnace suspended in the solar system. Wheat and bananas can grow under the light and heat of the sun. Our primates evolved from carbon-based single-celled organisms, processing steamed bread and cooked bananas with wheat to supplement energy, and then using the combination of muscles, bones and neurons to carry objects (cement and bricks) in exchange for some currency symbols to buy food for a living and continue to carry objects.

Therefore, although human beings are sorry, they are not pitiful.

If you have to find some poor people, I'm afraid there is only one kind, that is, people who have no ideals and waste their lives.
