### <div class=phishy>Introduction</div>

You wouldn't be wrong to infer that we're in an era of industrial automation (all thanks to the technology of Artificial Intelligence) which is the basis for the 4th industrial revolution. _But all these digitalizations and automations, do they pose any serious effect on our humanity? And how are they set to alter the course of our existence_? - All these; and more; would be considered in this post.

To say that we're experiencing (or rather; in the midst of) a massive revolution in the field of technology is to say the least. Take for example: in the computing world; just in the recent past, the computational power of systems that were considered as the world's fastest then only did a handful of calculations in minutes. But in this era, we've seen cray supercomputing beasts that are capable of cracking billions of calculations in just one split second - just like the newly launched Tianhe-2. Imagine what this would do to the computing world - the whole world's data can be processed in minutes, and this; no doubt; would create more human dependency on computers instead of our natural brain power.

Well, maybe this would give you a little shocker; according to this [report](https://www.cobbresearchlab.com/issue-2-1/2015/12/24/average-cranium-brain-size-of-homo-neanderthalensis-vs-homo-sapiens); it has been proven (based on the paleontological study of relevant fossils - skulls, particularly) that the Homo neanderthalensis (Neanderthal man) had a much bigger brain size when compared to the Homo sapiens. I'm sure you've already figured out what the cause of this could be. And not just that; even down the line to the extant Homo sapiens sapiens (modern man) there has been further dwindle in the size of the brain. What used to be up to 1500cc by volume, is now barely 1300cc on the average <sub>[[ref](https://www.dailymail.co.uk/sciencetech/article-1343093/Human-brain-shrinking-20-000-years.html)]</sub> - this can be directly queried on our over-reliance and over-dependency on computing devices.

I mean, why should I even stress my brain to perform complex mathematical tasks when I can lay hold on computers and calculators? - and that's how the brain size has so much degenerated. And remember the law of "Use and Disuse" by Jean Baptiste Lamarck that proposes that a body part not often used (or disused) becomes less consolidated upon, while the consolidation goes to the body part often put in use. That is why the arm you use favorably (to lift weights) would get bigger than the other arm over time. In the same way; since we now heavily rely on computing devices in lieu of our brain, why should you be surprised that it is dwindling? Take this scenario as an instance: The ancient hominid species; while leaving their territory for a "long walk", they would be very observant to eye-mark trees, landmarks, et al, so it would aid them in their return. But in this era, we would just pick up our GPS device and navigate our way to any place we want to go... but at the expense of our brain power and volume.

Still on the brain power; from personal experience; before I got my first smartphone, I had the phone numbers of all my direct nuclear relatives by heart, and I could also memorize my passwords (which are always uniquely long), but these days, I can barely remember a few, because I've saved all in my smartphone - I wouldn't have the need to stack up stuffs in my brain like before. No wonder there has been speculations that we; in this extant form; are actually dumber than before the advent of technological complexities. Though; by capability; the human brain has been proven to store up to 2.5petabytes of data in over 100billion neurons <sub>[[ref](https://www.scientificamerican.com/article/what-is-the-memory-capacity/)]</sub> -  To make these figures clearer: 1petabyte = approx 1,000,000,000,000,000bytes, that's an excess of billions of standard textbooks, but how much of it do we actually utilize?

If you've been following my blog lately, you would have discovered I once treated the effect of technology on our physical bodies as humans - like the evolution of humans with lesser muscle mass, because; obviously; machines have replaced the physical exertion of the human muscles, so it wouldn't be surprising if we become weaker with a more sedentary lifestyle. But away from these effects on our bodies; what about our environments, how has technology affected it?

### <div class=phishy>Digitalization and the environment</div>

Before the advent of technology, the majority of the noise and sounds we heard probably came from humans and animals alike. But in this era, the world is becoming heavily noisy - car horns, machine sounds, automobile noises, generator sounds, heavy industries, and all whatnot. No wonder the rate of noise pollution is on the increase. But more disheartening is the fact that some of these machines are powered by biofuel, and the by-products are released into the atmosphere, which causes heavy disruption of the balance of our ecosystem and also air pollution.

People living around heavily industrialized areas can barely breathe in clean air (maybe we should put some fresh air in containers and mail to them, lol). Take this instance: China has been considered one of the most industrialized countries in the world, and the major part of this is hosted in the city of Beijing. No wonder it has been said that the emission of pollutants there has been on the high side when compared to the rest of the world <sub>[[ref](https://www.cambridge.org/core/journals/china-quarterly/article/introduction-air-pollution-in-china/8D36F205FEC68513BC45E2DEC0F2AC26/core-reader)]</sub>. How safe would these people be in a couple of years from now if nothing is done about it?

Air pollutants are not the only culprit here; what about land pollutants? Okay here's another scenario: Nigeria has been among the top leading nations in the production and exportation of crude oil. But if you've ever had the privilege to be around some of these oil refineries and oil blocks, you would feel very concerned. Some months ago, a major oil-borne pipeline got ruptured along the Niger delta region, and this spelt a serious catastrophe - the ecosystem was heavily disrupted, people's farmlands worth millions were destroyed (of course, crops can't grow in oil)... and just as you would expect, when the rains came, these spills were washed into the body of water, and I'm sure you would know the effects it would have in the marine habitat - it was R.I.P to a great number of marine creatures.

<div class="pull-right"><center>https://i.imgur.com/J8MQSrR.jpg<sub><a href=https://pixabay.com/en/flooding-surreal-living-room-design-2048469>Pixabay. CC0 Licensed</a></sub></center></div>

More so, as by-products of these refineries and heavy industries, the release of greenhouse gases is inevitable. Okay, to a considerably fair extent, the presence of greenhouse gases is useful to the earth, if not, there wouldn't be anything to trap and retain the heat, and temperatures can fall below the threshold we can bear. But when these greenhouse gases become way too much in the atmosphere, what would happen? Of course, the earth would trap more heat, and the overall temperature of the earth would increase, leading to global warming. And when this happens, the icy caps begin to melt, and the coastal cities might go under water. A very minor case was experienced in the coastal areas of Lagos; Nigeria, some months ago, and an entire neighborhood got almost sunk. Imagine what would happen when the polar caps begin to melt from global warming - the level of the oceans and seas would increase, and it could be a permanent farewell to some coastal cities.

So as technology is advancing to next levels, it also delivers some devils with it. Well, maybe this is the price we have to pay for advancing technology. But one thing is sure; the purpose of technology has been to bring assistance to mankind, and I believe the advantages of technology far outweigh the disadvantages.

### <div class=phishy>Conclusion</div>

This era has been greeted with technological advancements, but at what expense? Okay, the truth is, there are "causes" and "effects" to everything. But I ask you; if you were to make a choice either to live in this era with all these technological whatnots, or to go back to the era of the earliest hominid species (maybe the era of the Sahelanthropus tchadensis) with zero tech, which would you prefer?
