AI, Automation, and the Future of Humanity
The new generation of AI-powered automation might completely redefine how most works are done. Will this be a blessing or a curse for humanity? What will be the fate of humanity?

In 2017, a survey conducted by United States’ Pew Research Center shows that the vast majority (~77%) of the United States’ population does not think that AI taking over human jobs could be a realistic and serious issue. ~14% of the United States’ population thinks that it is impossible for robots to take over human jobs.
“A roughly comparable share (77%) thinks this idea is at least somewhat realistic, and one-in-five indicate that the concept seems extremely realistic to them.”
As the use of AI continues to bloom in more industries, a fair amount of the global population is still under the impression that AI, like many other types of machines and devices invented in humanity’s history, will merely aid people’s work instead of outright substituting human workers. However, is that a reasonable estimation?
Traditional automation like automobiles and automated assembly lines have replaced many physical workforces, pushing the then-existing manual labor workforces into other industries. The new automation technologies also created more better-paid jobs, raising the living standards. This gave people the impression that new innovations will always create new and better jobs for people to move into. However, Kurtzgesagt has presented a prime example of how this is no longer the case with new types of automation in their video “The Rise of the Machines – Why Automation is Different this Time”:
“In 1979, General Motors employed more than 800,000 workers and made about $11 billion US dollars. In 2012, Google made about $14 US dollars while employing 58,000 people.”
In fact, some parts of the workforce in the transportation industry has already encountered issues when automobiles were invented. While humans could find alternative jobs, the horses could not repair cars, make food in drive-through restaurants, nor operate gas pumps. Consequentially, horses slowly faded into history. We, as humans, felt like the same will never happen to humans, but it will. That was just not our turn. GCP Grey has talked more about this in his video “Humans Need Not Apply” published way back in 2014, while also predicting that the humans will become the new horses.
The creations of new automation technologies have always taken jobs. In the past, humans could move to new jobs in new industries, but the recent automation technologies did not create enough new jobs to match the speed at which the population grows. The new automations are also getting better by the day and are able to do more and more jobs currently done by humans. Coincidentally, Google published its new AI research Pathways Language Model (PaLM) during the writing of this article. It shows you just how close AI has become to not only be able to do specific works better than human, but also able to think and talk like humans.
Even the creativity industry could be taken over by machines. Projects like MuseNet and the Deep Dream Generator can already give you an early taste on future arts. Out of sheer coincidence again (or is it?), OpenAI published their new AI image/art generation system DALL·E 2 during the writing of this article. You can see how easy it might be in the future to create art with AI – write a sentence and you can trivially blend multiple art styles together and create what’s in your imagination with no prior art experiences required whatsoever. At the pace of which AI is evolving, it is entirely possible that a significant amount of the population will be pushed onto a brink of losing their jobs in the foreseeable future, no matter how essential they are at the moment.
While talking about the difference bettwen the new generation of automation, it is helpful to take a look at what has enabled AI to be smarter than before. This might also hint us on how the roles of human workers will change in the future.
Conventionally, automation requries humans to teach computers what to do. This requires humans to identify patterns, indications, and techniques, then teaching them to the computers in the form of programming. In the end, the automation program is nothing more than a bunch if
statements. If humans cannot express the patterns requried for performing a task precisely using code, then this task would be difficult to automate. Take speech recognition for example. Humans can naturally recognize words, but it is difficult for us to describe using metrics and numbers what makes a word a word. Therefore, you will have a hard time building an accurate speech recognition program using conventional computing.

This is what traditional automation may look like
Machine learning (ML) and deep learning takes a different route. The core idea of ML is to digitize everything and finding patterns within the numbers. With speech recognition, a word’s pronunciation can be broken down into frequency, amplitude, and other metrics that can be use to numerically describe the word. Each of the metrics is a dimension of the information. ML then finds patterns within all these dimensions though looking at different samples of data. For example, you ask the machine to watch the frequency and amplitude of the voice, and then feed it n samples of pronunciations of the word banana
alongside n samples of pumpkin
, so it will find what is the pattern that makes the word banana
banana
instead of pumpkin

This concept of data-driven problem solving can be applied to solve all kinds of problems. As long as it is possible to collect data about the problem and define what success looks like, ML can find a pattern that will solve the problem given enough time and resources. Of course, the accuracy of the solution and resources required to tain a workable model may vary depending on the “difficulty” of the problem, but it will make lots of previously-unsolvable problems possible to solve.
However, a side effect that stems from this approach is that it would be difficult for humans to understand or explain the underlying mechanics of how and why decisions are made by a neural network (NN), the backbone of ML. For instance, a NN may classify a cat as a dog, but the final output does not explain why the image is miscategorized. Nevertheless, there are still ways to debug NNs. Examining the outputs of each building block would provide an abundant amount of information on what patterns it has extracted from the input image, which can be used to guesstimate what went wrong. More recent researches like this and this are also helping humans to better understand the NNs 1.
In the near future, it is almost without a doubt that AIs will replace more humans in more industries. There will be more AI experts in every industry to train and supervise AIs. These AI experts will likely have little to no knowledge about the industry of which their AIs work in. Some original workers in the industry will get to keep their jobs because they cannot be replaced by machines or replacing them are not cost-effective. These are likely the only reasons why they get to keep their jobs.

A new type of job may be created. Workers with expertise in a specific industry may be hired as consultants. Their job is to help the AI experts to understand certain niches in the job and to better develop ML models.
Let’s see an example with cybersecurity, my own field of expertise. Right now, managed security service providers (MSSP) usually hire lots of junior security analysts to identify threats in security logs. In the future, all the junior security analysts will no longer be needed. A machine will plow through all of the logs at accuracies and speeds unmatchable by thousands of human analysts.
The ML model used by this machine will be the most valuable asset of the company. MSSPs mainly compete how good their models are, with metrics typically being accuracy and speed. Every MSSP will have several AI experts that continue to optimize their models. Only very few IT operation management (ITOM) personnel and security experts are needed to maintain the underlying infrastructure and help the AI experts to train the models.
As AI technologies continue to advance, at a point a little further in the future, most of the work might be done completely by robots. Humans are naturally limited by their age and the speed of which they can learn, so a person would need to go through a cruel amount of learning and training to be able to out-compete the intelligence accumulated by the machines, which never lose their memories and continue to think faster and perform better.
Eventually, the vast majority of jobs will be done by machines, which may sound like it is a bad thing for humanity. However, this may be the inevitable for an advanced civilization. The Kardashev scale defined three types of civilizations. It is highly costly if not impractical for humans to reach type II civilization by building a Dyson sphere with pure manpower. Automation almost seems inevitable. Advanced automation may be required for any advanced civilization.

Despite automation might produce a decline in employability of humans in the near future, as we move further into the future, the entertainment industry might flourish. Space exploration and space colonization may create almost infinitely more new jobs once the current-generation of automation help humans finish the research of better spaceships.
Even if all human lifeforms get entirely replaced by machines in the end, we have still managed to create a new species that is better than us, which is quite an achievement. Nonetheless, machines can also have emotions and can carry on our legacy and wills. When they become intelligent enough, they may even be more like humans than us.
