As people rely more and more on technology to solve problems, the ability of humans to think for themselves will surely deteriorate.
Technology has proved to be the most important pillar on which the world resides today. However, as of everything, technology comes with its boons and banes. To say that relying on it to solve problems would decrease the human ability to think would be too extreme to be correct, and at the same time, it is not entirely wrong either. There are several instances where indeed the use of technology has led to people becoming completely dependent on it, but at the same time, there are many other instances where human thinking has not deteriorated by technology.
If we take a look at the current trend of communication and technology, lots of people today own a smartphone, which, by far, has impaired human thinking the most. One perspective that supports this is that millions of people depend on how the application developer thinks. We could take the calculator for an example. It is not unusual to see people using their calculators for even the simplest of calculations. Thus, technology has made the human lazier than before. He refuses to think because he has at his dispense a machine that can do the thinking for himself. Consequently, we waste a lot of time using the benefits of technology for very trivial operations.
On the other hand, there are numerous instances where technology has in fact complemented human thinking, or at the least, has had no effect on human thinking. For example, transportation would not have existed without technology. Human thought as to how to make it more intuitive, for example, learning to make airplanes streamlined by observing the structures of aerial creatures, or the submarine by seeing the anatomy of fishes, certainly shows that the ability to think has in fact increased manifold. Yet it saves huge amounts of time for us, helping us in working constructively without wasting much time in transit. Communication is yet another area where technology has indeed proved helpful and has not impaired human thinking. In fact, it has boosted human thinking to achieve better communication methods, which we can see if we compare the technologies of today such as Wireless, Bluetooth and mobile communication to those about two decades before.
Technology also helps us in conceptualizing numerous things in a more visual way, helping in effective human interaction. Without technology, many concepts which were in blueprint earlier, would never have been materialized. We can see this clearly from the numerous blueprints made during the era of Da Vinci, and how so many of them have been realized lately. Also, with the increase of technology, people now have much more free time to innovate for themselves, so that they can come up with new solutions, and they also have time to lead their lives more peacefully, by leaving the work to machines, which in some cases, proves beneficial, because of the fact that a machine is less prone to making errors, unlike humans, who tend to make errors when they are tired or have more than one thing on their mind.
To conclude, though it might be true in a small number of cases, the areas where technology boosts human thinking exceeds by large. Hence the advent of technology cannot be considered to deteriorate human thinking.
