The reasoning about the progressive introduction of photo camera (one at a time) and the commercial effect of it

I bring to your attention that unpretentious sequence of events that I noticed and stated when we discussed in February whether it is appropriate to buy a tablet or wait for a while. I supplemented the following consideration in comparison with the February one: it concerns not only tablets, but also modern clever mobiles.

We will talk about photo cameras.

Many people remember that initially mobiles did not contain photo cameras at all, but this situation soon changed; The plates initially almost all contain them.

First, in mobile phones and tablets installed only one photo camera (from the back) for photographing and video recording.

Then, in the mobile phones and tablets, the second photo-video camera (from the front side) for video chats also began to appear.

The introduction of stereo displays (which some also call for 3D displays) is already taking place - therefore, over time, we can also expect a third photo camera (from the back) for stereo photography and stereo video recording, and then a fourth photo camera (from the front) for stereo video.

Then, the fifth and sixth photo video cameras are also likely to appear in order that the stereo effect is equally provided with the “portrait” and the “landscape” orientation of the mobile phone (or tablet) relative to the eyes. ( Koshelew , however, assumes that stereo pairs of photo camera cameras can be made turning instead of turning stereo pairs into stereo pairs - this will make the construction cheaper, although it will certainly decrease its reliability, convenience and speed of reaction.)

Zinically I assume that at each of these six steps, the manufacturers of mobile phones and tablets want to see each of us buying the next new mobile phone and tablet (upgrading old mobile phones and tablets will, of course, be impossible).

It is good that such a seventh step on this path, which would have universal appeal, is not easy to imagine. Although, I suppose, fans of photo and video recordings would like a lot of a mobile phone or tablet, which automatically puts forward a telescopic tripod in case of need (a half or two meters above it), equipped with twelve additional photo cameras, located at the apexes of the geometrically correct icosahedron, and allowing for panoramic photography (as in Google Street View or in its Yandex counterpart, for example) or panoramic video (as in videos on the Ryubin's Panorama Laboratory website, for example).

However, this natural seventh step remains a distant future.

Know, than the scenario stated by me is useful? Armed with them, all of you can exercise willpower and save money in a variety of ways — for example, temporarily refraining from buying a device with three photo-video cameras until four-chamber devices naturally appear.
