Technology will always be "just a tool." By its nature, it is morally neutral. The use of technology for good or for evil reflects the morality of the people deploying it.
Explosives, baseball bats, water, radios, software. All have been used for noble purposes and for evil. That does not impart morality to the technology.
Whenever I see someone saying something like "just a tool" with regard to technology, I always want to recommend a thorough read of Marshall McLuhan's "Understanding Media" ("The Medium is the Message" and other adages).
I think you've got it precisely the wrong way round: it is not the morality of the times that is reflected by the use of technology, but morality that reflects current technology.
The French and American revolutions that began the current age of modern democracy are, for example, unthinkable without the printing press. No newspaper, no democracy. It needed the equalising force of mass-copied text to abolish the sacred order of monarchy in people's heads. Similarly, it is hard to imagine fascism without the preceding inventions of radio and cinema. Or J.F.K. without television.
Culture, society, customs, morality - everything that has to do with what we call 'evil' or 'good' - is fundamentally a reflection of their surrounding media. Morals under the conditions of television will be different from morals under the condition of the world wide web.
One can see that we are currently struggling to adapt our morality to a new media reality by the invention of new words ("fake news", "filter bubble", "clickbait", "post-truth") to describe it; the old ones are insufficient.
I propose that rules and guidelines that emerged under the conditions of offline media will leave us vulnerable to the dark and dangerous sides of online media. We should develop new ones.
The medium is that which spreads the message. Since the mediums operate differently from each other, only certain types of messages can be transmitted over each one.
Before written systems, a message could only be spread by word. The message could be stopped by disappearing the person speaking.
Before print media, messages could only be written down by a scribe or learned person, and the message could only be read by another scribe or learned person. Or messages could only be passed in the form of images. Those messages could be stopped simply by burning/destroying the written/etched copy that existed.
Before the telegraph, messages could only be delivered in person, on foot or on horseback or by ship, limiting its rate of spread to those transportation speeds. Those messages could be stopped by intercepting the delivery, or controlling the territorial borders.
Before radio and telephone communications, transmitted messages could only be read by telegraphists. The messages could be stopped as long as there was no telegraphist at the time of message transmission, or if the telegraphist lied about the message.
Before televised media, only messages in the form of voice or text could be transmitted far distances, so only voice or text was consumed. The information bandwidth was extremely small, although fast.
Before internet media, only audio, video, or text could be transmitted. The information bandwidth increased with video, but these high information channels were only controlled by media elites and governments.
With internet media, internet isn't a message you consume, internet is something you participate in. The instant participation of the global population in a single activity is something altogether new that is a step-change in what has been available, and no prior medium could have prepared us for this age. The old media elites still want to control what messages are dispersed, but the new medium doesn't cede that control easily.
Maybe, if you define 'technology' to be just things like instruction sets and transistor geometry.
By that narrow definition, phones contain more than technology: they contain policy. A phone loaded with addictive games embodies a policy of maximizing screen time. A phone with clickbait on its lock screen is designed to take up your time and bathe your retinas in bullshit. While the transistors are neutral, the policy is harmful.
As it happens, these policies are often set by people that mostly work on technology, so they get lumped together. From outside, people see the technology industry being responsible for all of it.
There's a saying "When you let the camel's nose into the tent, the rest of him follows." If a technology has so many awful capabilities, then there ought to be a good reason to tolerate its existence.
I hear you, its like saying alcohol is just a chemical. Which is true of course. But I think it's naive and idealistic. Taken to an extreme, you could say people are just chemicals and electrical impulses, right? But that's crazy.
