 Today's computers are really smart. They can see things, they can speak, and they can even play the ballgame of Go. And this is remarkable because Go is such a complex game. To be a good Go player, you have to rely on intuitions. Computers do not have intuitions. That's why previously people saw that computers could never beat a good human player. But just two months ago, a computer did beat the best human player in the world in a game of Go. So now it seems that computers do have acquired some sort of intuitions. And the reason behind all these amazing breakthroughs is machine learning technology. Using this technology, we can feed a vast amount of data into a computer. And then the computer can learn by itself the hidden patterns in the data and make predictions. I think artificial intelligence is going to have an impact on knowledge workers in every sector. No one is safe. But the extent of the impact depends on the nature of that sector. For example, if we are talking about analyzing financial data like stock prices, computers can do that. In fact, computers can do it better than human beings. And that's why the majority of security transactions in the world are now done by computers, not by humans. But for some professions like law, it is more difficult for computers to do. Because legal reasoning requires common sense. And common sense is based on a wide range of knowledge like history, us, music, science, sports, all of it. Computers do not have that general knowledge, so they don't have common sense. But now scientists are trying a number of ways to solve this problem. One of the ways is to convert each word into a long series of numbers. In other words, we are translating the natural language into a language which computers can understand. And hopefully one day computers can just go out and read all sorts of materials and gain common sense. We are not there yet, but we are getting there. If computers become truly smart in the sense that they can read, they can understand, and they can reason, then they can do a lot of things from a lawyer's perspective. I can let computers draft contracts, do diligence, or even give me a summary of all the relevant cases on a particular topic. Actually, we can take this idea one step further. And let's imagine that a computer reads all the cases and the statutes and textbooks, and then the computer will become an expert in the field of law. In a sense, the computer becomes a robot lawyer. It can provide legal advice. It can do legal reasoning. And in fact, currently, one of the problems with our current legal system is that people need legal advice, but they cannot afford it. So maybe a robot lawyer is the solution. And in the financial sector, actually, this is already happening. Computers are already providing investment advice at low cost or free to retail investors. Once computers can do things on their own and make decisions on their own, I think we then have to consider a serious question. That is, how much responsibility we can give to computers? In other words, what are the decisions a computer can make and what are the decisions only a human being can make? I think it's quite safe to say that we can allow computers to drive a car or fly a plane or even perform medical operations. But on the other hand, I think we should never allow a computer to decide the fate of a human being, like whether that person should be killed or sent to jail. But there will be some tricky questions, like can we allow a computer to decide whether to build a new bridge or to lower the interest rate? Those are difficult questions and I think we need to start thinking seriously about them. Artificial intelligence will transform the job market in the next 10 or 20 years. There's no question about that. For the legal profession, we are facing two types of questions. One type is whether the new laws or rules we need to design or create to cater for this new phenomena. And the other type of question is how legal professions can use the new technology to increase the quality of legal services we can provide to our clients. But the AI future can be a bit scary, but it's also very exciting to me. For the first time in human history, machines not only enhance our physical power, but also our mental power to think and to reason. The journey to artificial intelligence will push the boundary between machines and humans and lead us to a better and deeper understanding of the true meaning of humanity.
