What do you think about it? I believe this whole discussion is senseless. If you want to understand more please read the article below

First I think you should stop promoting your blog this way, with discussions that have been covered a hundred times already...

Second, there is a paragraph in your article that is non-sense...

As said before, theres a market tendency that leads to manufacture chips more efficient that consumes less energy. Probably the candle manufacturers would use the media to spread the same argue decades before: the light bulb will cause the environment ruin in a matter of years.

Bitcoin mining is not like using light bulbs, there is absolutely nothing like it.

When you mine, you have costs and revenues.
If you can earn a revenue of 10 000 with 9 000 spent on energy you are going to mine.
It doesn't matter how efficient those miners are, nobody cares about efficiency alone, it all comes to how much kwh spent on how much $ earned.

So as long as the daily reward will be 100 million people might spend 90 million on energy.
If it goes to 1 billion they might burn 900 million worth of it.

It's not like a light bulb where you can light your room cheaper, if a miner will be twice as profitable, they will simply buy twice as more and in the end consume the same amount of power.

Miners have become more efficient for 9 years, it didn't stop power consumption going up.

When the S1 was launched it delivered 180 GH/s at 360 W
The S9 comes with 13 TH/s at 1375, the efficiency went 20 times up.
But the global hashrate went 3 000 !!!!!! times.
