The Feeling Machine

‘Cogito, ergo sum (engl. ‘I think, therefore I am’)’. For decades authors and directors have dreamed about the self-aware machine, letting their imagination run high. With AI-technology fast developing, could it actually happen? Can a machine actually become conscious of its existence?

In the 17th century, long before the first computer was developed, French philosopher René Descartes described his first principle of explaining what proofs the existence of a being. Could ‘Cogito, ego sum’ soon be applied not only on humans but machines as well?

This much debated and highly sensitive question of our times was put to discussion on Sunday at the annual DLD Munich 2018 conference. Under the topic ‘Cogito Ergo Sum – Can A Machine Be Conscious Of Its Existence?’ Ina Fried, chief technology corresponded for Axios and editor of its daily tech newsletter Login, interviewed Alexander Del Toro Barba and Prof. Jürgen Schmidhuber. Del Toro Barba is Head of Product at VisualVest, a digital banking platform founded by the German asset manager Union Invest, which uses robot-advisors. Schmidhuber, named the Godfather of AI by the New York Times, and his research group at the Swiss AI Lab IDSIA and TU Munich developed the Deep Learning Artificial Neural Networks.

Can a machine or computer feel emotions?

Feeling emotions, according to Jürgen Schmidhuber is no thing of the future: ‘We already have emotions as a side-product of learning processes.’ He and his team equip the robots with pain-sensors. If they bounce against something the sensors sends a negative signal. ‘How do you know if someone feels pain or just pretends to feel pain?’, Ina Fried asks. Both Alexander Del Toro Barba and Jürgen Schmidhuber acknowledge that it is hard to differ between the two. The key is, Jürgen Schmidhuber underlines that their robots can act emotionally and they do. At the beginning of a learning process they do not know how to avoid certain situations, by time they learn to. The goal: To maximize positive feelings and minimize pain.

In his office, he says, they have a robot that get’s hit by a co-worker on the head every morning. Over time he developed behavior that humans would see as fear: Avoiding and hiding from that person.

Is it possible for a machine to develop a consciousness?

‘There are different levels of consciousness’, says Alexander Del Toro Barba. Thus when talking about it, one has to differ between human consciousness and the one robots might experience. Jürgen Schmidhuber agrees: ‘Consciousness has no universal definition.’ This still seems to be a thing of the future, as he adds: ‘it is easy to create a system that (…) becomes a prediction machine of what is going to happen next.’ Which, according to Schmidhuber, can influence to the state that a machine is thinking about itself.

Where are we today?

‘95 % of commercial AI are now assistants for users and companies’, Prof. Schmidhuber says. Artificial Intelligence like Long short-term memory (LSTM) units make it possible for advices like smartphones to make your life easier such as understanding speech or translation.

A technology, as Alexander Del Toro Barba states, that was also used on Tay, an AI-Chatbot developed by Microsoft, who should learn on Twitter how young people communicate. Within 24 hours Tay tweeted racist statements. Which brings up, as Alexander Del Toro Barba mentions, the question whether we should introduce them to ethics.

Should AI be introduced to ethics? And if so, which ones?

Ethics and moral ideas vary depending on region, religion, social and political views. Alexander Del Toro Barba: ‘Will there be AI with ethic views of the Vatican, ones with Chinese and some with Islamic worldviews?’ He goes even further: ‘Will a machine one day question its values, that were programmed into it?’

Jürgen Schmidhuber is rather optimistic: ‘If you want to build a smart machine you’d better give it the freedom to invent it’s own problems.’ This includes also values. As there is also not one single uniform set of values in a nation, but competing ideas and the AI business is structured rather democratically, he is sure there will be various sets of values as well.
