1 What will restaurants be like in the future?

I suppose quite a few things could happen, one of which might be that waiters will be replaced by robots, because by doing this, restaurants will reduce their labour costs. So that's one thing, and on top of this, I imagine it's also quite possible that we will see an increase in the number of high-end restaurants, simply because people's living standards are getting higher and higher. Of course other things are bound to happen, but right now this is all that comes to mind.

2 What websites will be popular in the future?

Well, if we look at what's happened in the last few years, I think most people would agree that social networking sites have become incredibly popular, and I would say this trend is likely to continue  into the foreseeable future, simply because people enjoy spending time chatting with their friends, whether it be in person or on the Internet.

3 How do you think work will change over the next few decades?

That's a good question, and thinking about it, I guess one thing that could happen is that more people might start working from home, simply because it's becoming more and more inconvenient travelling to work due to traffic congestion. So that's one thing, and I guess it's also quite possible that work, in general, will become more internet-based, because the influence of the Internet on people's work has increased incredibly in the last 10 years or so, and I can't see this changing. I mean, more or less everything we do now can be done on the internet, and because it's so convenient, I would say it will play an even bigger role in our lives in years to come.
