Co-evolution of Humanity and Technology

By jasonz

As much I enjoy reading Norman’s thoughts on the co-evolution of humanity and technology in his article from The Invisible Computer. I find his views on the technological impact on humanity to be a bit pessimistic. He sees technology and machines as some foreign entities that are beyond our control while overlooks many aspects of technology such as its potential as a tool for creation and knowledge transfer.

While Norman makes a good point suggesting people are” forgetful of details, with a poor sense of time, a poor memory for facts and figures, unable to keep attention on a topic for more than a short duration, reasoning by example rather than by logic, and drawing upon our admittedly deficient memories of prior experience.“ I think comparing humans to analog is a questionable analogy. Analog technology was created for the purpose of storing and reproducing information in a systematic way. It is as much machine as any modern technology, but dated. Calling ourselves analog is suggesting we are still living in the past. In Norman’s view, ”people are analog, insensitive to noise, insensitive to error. People extract meanings, and as long as the meanings are unchanged, the details of the signals do not matter. They are not noticed, they are not remembered” I find it hard to agree with this statement. While we do have high tolerance for errors, we are sensitive to noise, sensitive to error. Our accumulated knowledge and experience have taught us noise is detrimental to decision-making. We spend tremendous amount of time and effort to minimize errors through documenting, reproducing and examining data to identify patterns. With the help of technology, we are constantly learning from our mistakes and trying to make sense of world through analyzing new and historic information.

Norman points out that “human beings are the results of millions of years of evolution, where the guiding principle was survival of the species, not efficient, algorithmic computation.“ Norman would be right if we still live in prehistoric times as hunters and gatherers. When people started forming societies that were organized around agriculture and institutions, our priorities shifted. As population grow so does our need for stability and predictability. Our obsession with efficiency and predictability can be traced back to our need to make better forecast to increase food production in order to sustain an ever-growing population. Our obsession with stability is needed for governance and establishing orders. Human beings have “co-evolved with social interaction, cooperation and rivalry, and communication”. Society would not have thrived and progressed without stability and improved efficiency in tools making and resource utilization made possible through technological progress.

Norman points out that technological progress and our obsession of efficiency in production have reduced us to just machines in an assembly line “hence too came the dehumanization of the worker, for now the worker was essentially just another machine in the factory, analyzed like one, treated like one, and asked not to think on the job, for thinking slowed down the action.” While this is somewhat true, technological progress has the potential to save us from dehumanization by automating low skill jobs and give us more time to focus on creative tasks that require cognitive skills. Although there have been numerous debates on the economic implication of job displacement by technology, improved efficiency through automation have make goods and services more affordable and accessible. Advances in technology have also created many job opportunities for the creative industry and information professionals. Norman points out the issue that technology has moved so fast that we are unable to keep up. “The slow evolutionary pace of life is no longer up to the scale and pace of technological change. The accumulation of knowledge is enormous, for it increases with every passing year. Once upon a time, a few years of schooling — or even informal learning — was sufficient. Today, formal schooling is required, and the demands upon it continually increase.”  While I believe Norman’s statement resonates with many of us who are always in pursuit of new knowledge to stay competitive in the world. I feel that knowledge does not accumulate perpetually. Knowledge becomes obsolete as we find better ways of doing things. For example, while it is helpful to understand machine codes, not a lot of software engineers use machine codes for programming. New knowledge supersedes old knowledge. Whatever knowledge we find relevant today may not be relevant a decade later. Our pursuit of knowledge can go as far back as the prehistoric times when we sought ways to identify weather pattern and better farming techniques. Technological advances facilitate the transfer of information to help us stay informed of nascent and relevant knowledge. There is no shortage of vast libraries of digital information and self-guided online education. The sufficiency of education is subjective and highly dependent on individual need. It is up to our individual choices to decide whether to take advantage and adapt to the ever-changing world.

Norman brings up some interesting points but I find his views to be a bit dated. I do agree with the fact that technology needs to be created in a way that should complement us, but I find it questionable that “we are compliant, flexible, tolerant. Yet we people have constructed a world of machines that requires us to be rigid, fixed, intolerant.” Machines do not require us to be rigid and intolerant of errors. Machines are programmable and follow rules set by humans. Machines are as flexible as we build them to be. The way machines are built is a reflection of our capabilities in applying knowledge to build tools to advance our cause. With advances in digital technology, electronic devices have become portable and computer processors have become much more powerful. The costs of producing and storing information become much cheaper and access to information has become much easier. Without accuracy and precision, much of technological progress that we have come to appreciate would not have existed today. Although “digital signals are limited in values”, they have enabled much creativity and information freedom. As complex as computing devices have become, they are still largely single-purpose tools that cannot make decisions and only capable of performing tasks in repetition. Machines are tools that help us to create better tools. While I do agree with the fact that “We have constructed a world of machinery in which accuracy and precision matter. Time matters. Names, dates, facts, and figures matter. Accurate memory matters. Details matter.” I don’t think we have forgotten we are still good at experimenting and inventing through trials and errors.
