Let us assume that we do not yet have a time machine, not because time travel is not possible at all, but because it is not possible in physical terms.
In this paradigm, the hypothetical temporal traveler would be sent into the past or future by a time machine that would be anchored to “their” present.
And since we have already established that a time machine, should it exist, would be used infinitely, the corollary is that any traveler could not be present in the non-native timeline in their physical form.
After all, we occasionally hear from a madman who claims to have come from the past or from the future; we do not hear from hundreds of them. And the few we hear from are always quite ignorant of historical facts, and incapable of getting right the most pedestrian of predictions.
Therefore, if time travellers exist, they will be more like observers; they can see other timelines, but not interact in them. Or if they do interact, it would be in a way that would be indistinguishable to what we call “the supernatural”; for us, events occurring from their actions would look like an inexplicable phenomenon.
But here we return to the problem of infinite reuse; sure, whenever it would hypothetically be invented, a time machine could be considered a dangerous and difficult instrument to produce. But let’s not forget how little time it took for us to go from a world where there only existed two atomic bombs, in the possession of a single country, to thousands of them scattered all over the world.
Technology multiplies exponentially. If it were possible to send people to the past, and if the manifestation of it their actions would equate to what we call the “supernatural”… Every house would be haunted.

It’s not possible to build a time machine.
If it was, we would already have one.
From the moment a time machine exists, people will use it infinite times. If time-travel is used endless times, sooner or later, by intention or accident, the means for such will end up in “our” hands. Or those of our ancestors.
The other possibility is: from the moment one goes back in time, one creates a new universe. Which means that, for the practical purposes of ordinary 4-dimensional mortals like ourselves, who inhabit this universe exclusively… There is not and will never be a time machine.
The third possibility is that the time machine, and they who use it, do not move through time in the same plane of existence as us, are not perceivable by us in any way.
More on this in an upcoming essay …
The incentives of the Internet of today aren’t aligned with quality. The values here are quantity and velocity.
What this means is that it is beneficial for someone with no fame to write a quick article or record a basic course on something that has been developed for years by someone else.
But it doesn’t stop there. I’ve seen (this is often the case in Medium) people writing articles about the articles of others. Invariably, the “others” are known authors or gurus. The new authors have nothing to add, they just seek fame (or mere credibility) by association. It’s a culture of repackaging.
Worse, something is always lost in the translation. The exercise may be valuable to the writer – after all, we learn best when we write what we learned in our own words – but as far as the net total of internet knowledge goes, it only serves to muddy the waters.
It’s always better to drink straight from the source.
