Modernity is bad period, not just for dharma practice, but for everything. Nothing good ever came from the myth of linear teleological progress through the march of time, induced by new technologies.
This is a great topic, I am not gonna bother to read every previous reply, because I find most here use Buddhism as their form of escapism. "Samsara is samsara" or just invoking samsara is one of the most popular catcheisms on this site, sadly. It is a great excuse to refuse to analyze your present epoch and also lazily refuse to realize what good is being lost every day to allow the continuing sacrifices necessary on the altar of a narrow type of progress, peculiar to technological civilization. In modernized societies, most people spend a great portion of their lives partaking in escapism as a necessary adjunct for their mere continued functioning in society:

Consider the average man as he comes home from his job. Very likely he has spent the day in a completely hygienic environment, and everything has been done to balance his environment and lessen his fatigue. However, he has had to work without stopping and under constant pressure; nervous fatigue has replaced muscular fatigue. When he leaves his job, his joy in finishing his stint is mixed with dissatisfaction with a work as fruitless as it is incomprehensible and as far from really productive work. At home he "finds himself" again. But what does he find? He finds a phantom. If he ever thinks, his reflections terrify him. Personal destiny is fulfilled only by death; but reflection tells him that for him there has not been anything between his adolescent adventures and his death, no point at which he himself ever made a decision or initiated a change. Changes are the exclusive prerogative of organized technical society, which one day may have decked him out in khaki to defend it, and on another in stripes because he had sabotaged or betrayed it. There was no difference from one day to the next. Yet life was never serene, for newspapers and news reports beset him at the end of the day and forced on him the image of an insecure world. If it was not hot or cold war, there were all sorts of accidents to drive home to him the precariousness of his life. Torn between this precariousness and the absolute, unalterable determinateness of work, he has no place, belongs nowhere. Whether something happens to him, or nothing happens, he is in neither case the author of his destiny.
The man of the technical society does not want to encounter his phantom. He resents being torn between the extremes of accident and technical absolutism. He dreads the knowledge that everything ends "six feet under." He could accept the six-feet-under of his life if, and only if, life had some meaning and he could choose, say, to die. But when nothing makes sense, when nothing is the result of free choice, the final six-feet-under is an abominable injustice. Technical civilization has made a great error in not suppressing death, the only human reality still intact.
Man is still capable of lucid moments about the future. Propaganda techniques have not been able wholly to convince him that life has any meaning left. But amusement techniques have jumped into the breach and taught him at least how to flee the presence of death. He no longer needs faith or some difficult asceticism to deaden himself to this condition. The movies and television lead him straight into an artificial paradise. Rather than face his own phantom, he seeks film phantoms into which he can project himself and which permit him to live as he might have willed. For an hour or two he can cease to be himself, as his personality dissolves and fades into the anonymous mass of spectators. The film makes him laugh, cry, wonder, and love. He goes to bed with the leading lady, kills the villain, and masters life's absurdities. In short, he becomes a hero. Life suddenly has meaning.
Ellul, Jacques. The Technological Society. p. 376.
According to Ellul, it is foolish to analyze modern society with terms like capitalism or communism, rather one must speak of a unified technological society that seeks only efficient technique. "In our technological society, technique is the totality of methods rationally arrived at and having absolute efficiency (for a given stage of development) in every field of human activity." No one around me thus has any other type of knowledge than that demanded by technique: to be a good neighbor, to be a father or mother, as they have specialized their whole lives to be excellent workers and consumers of goods and services at the expense of everything else. The average person around everyone on this site is so disconnected from natural processes, any sense of community. It is so frightening to reflect upon, that it would cause total social paralysis if it was given the weight it was due, but most use escapism, to hide from such realizations, and on this site, that escapism is Buddhism.
Lots of research shows that modern devices and mass media create a new type of cybernetic person that cannot maintain single-pointed focus on anything, especially any difficult subject, but this new type of man excels in multi-tasking, juggling many tasks poorly as never before. Everyone has seen what results this has produced, and everyone tries to hide from their true horrific magnitude. I am sure many here know too many folks who even when you are with them, they have to have their cellphone out on the table, or fidget with their cellphone. That is just their constant reminder that they are always looking for the next better
person to contact, or perhaps that they cannot be still in any moment without movement or anticipating who next will contact them, or who they will contact next. Any concerted concentration is now impossible for a growing number of people. Also anything requiring the slightest effort like walking a mere three blocks for most suburban dwellers or dealing with the exigencies of extreme weather for several hours, is also not possible for most, when technology can subsume those problems for them.
