Human history's intrinsic nature is based on our own curiosity with which we could advance our own technology. That very necessary usage must be promoted by daily necessary necessity.

Our disease reality must promote hospital's presence.

Necessarily, our human survival history's very another necessity is obviously reacting each demarcated domestic unit as nation's security as the knowledge for preventing any foreign military from executing any invasion.

By the way,  for airplane pilots, aviation technology must need any course abiding each point's own weather condition. That necessity is the same either at sea, ocean route, afterward, railroad's it.

Any transmitting technology was progressed with that necessary usage.

Non the less, these all technological usage was for the first time the applicable usage from originally military necessary usage.

Though, any these days' generalized aviation, navigation, sea route voyage technology must have originally the military necessary technological usage. And for informing any weather condition, though necessarily, any each occasionally necessary dispatched runner was original messenger e.g. at Greece civilization, Rome one, or so.

Afterward, navigation system's necessity urged any compass technology's pioneered progress. First bearer was Arabic. Mathematics's progress was first left to Greece. But navigation's advancing necessity was demanded for human history at the eras after Greek civilization or so at first Islamism's emerge by Alabic, though, Mathematics's history's middle ages bearer was them.

In fact, necessity is mother of invention.

And these days' all private usage of transportation system was generalization from any military technology and strategical application.

Transmission technology is the same.

Transportation, navigation, an air route usage are all for the first time, originally, any now fixed generalized convenience is what was generalized legacy from logistics with originally military necessary knowledgeble technology and transmitting necessity's product caused from wireless transmission technology.

20century's greatness was that generalization to general citizens for general usage. Ford's car invention and Edison's light bulb invention were about same agae. Though essentially, military technological applications and paralleled running general citizens usage at necessary applications are synchronically made and running to reality for human history's necessity.

Meanwhile, Mathematics' history's next phase was entrusted to first French, afterward Indian.

French's historical appearance must have reasonable context derived from modernized citizen's society's birth with social reality for human cultural scientific necessity and accelerated speed of human civilization's daily usage of convenient tools and products accompanying statistical necessity for capitalism civilized knowledgeable technology's progress necessity.(manufacturing needs statistical knowledge and idea)

Then, at last, this article's mainly cardinal mentioning is started.

Highly progressed capitalism's general citizen's necessity for daily mainly urban area convenience abiding progress drove more correctness necessary precisely demanded calculated numerical sum outputting which promoted Indian genius mathematicians' appearance.

With these circumstances derived from historical background, generalized consumptive society's fixation must have prompted many superior pioneers with computer general usage applications. There, US transmitting technological contribution's appearance was made at human history.

Programmers, system engineers, controlling engineers or so were demanded by totalled global usage necessity. Generalized technology's general commodities manufacturing necessity drove more easily consumptive commodities which were mainly entrusted to these two decades' legacy with any kind terminal usage invented by mainly US pioneers.

Anybody can up any message so easily at any SNS site. Thereby, necessarily, very frequently easily upping any remark necessarily makes any active user which could be recognized by worldwide extent for any other user for SNS sites.

That frequent sites users must output any other criticizing user. Their massively simultaneous culmination and harsh derogatory personal attacks could occasionally sacrifice remarkably heavily frequent user.

That so atrocious harsh culminating aggression consequently outputted ones who committed suicide at UK, Japan, or so.

Very easily operating occasion's strict acquisition must have impacted very usefully human goodness which must be made as positive prevailance.

Nevertheless, meantime, either aggregated some very seriously mentally damaging must be done to specifically nominated user of any SNS.

In other words, any great prevailing of convenient tools of scientific usage dimension must drag very humanitarian wonderful fruitage for human society and simultaneously very negatively judged maltreatment to enthusiastic user of SNS sites.

Though, simply contemporary 21century's society's own convenience must have very seriously regarded double edged sword. And that reality's absorption in addicted daily habitual life mode easily makes anyone's mind satanic sadist mind and spirit.

And that affected negative case must never have age difference. Not only normal adults but also infantile children, very younger youth generation ones included.

(Irregularly continued)

Appendix; Consequently, nowadays' us have very emergent necessity in formulating for our own prevention us from executing unnecessary violent abusing for individual personal attack.

In other words, in any field, these days' human need ethical norm for controlling any seductive unnecessary upping of tweets.

Additionally, these days' east camps' Russia's globally regulatory illegal invasion is sustained by either individual usage technology of hucking as misusing for private usage of transmitting.To these, not only regulations but also ethical norm as some other formula are needed.
