Last week I got to do my third Ask Me Anything session on Reddit.
Here’s a run-down of all the questions I had time to answer.
QUESTION: 2015 will mark the 30th anniversary of Microsoft Windows. What do you think the next 30 years hold in terms of technology? What will personal computing look like in 2045?
BILL GATES: There will be more progress in the next 30 years than ever. Even in the next 10 problems like vision and speech understanding and translation will be very good. Mechanical robot tasks like picking fruit or moving a hospital patient will be solved. Once computers/robots get to a level of capability where seeing and moving is easy for them then they will be used very extensively. One project I am working on with Microsoft is the Personal Agent which will remember everything and help you go back and find things and help you pick what things to pay attention to. The idea that you have to find applications and pick them and they each are trying to tell you what is new is just not the efficient model - the agent will help solve this. It will work across all your devices.
QUESTION: Hello Mr. Gates, what is in your opinion the main obstacle to the success to poop water machine? and how can we overcome that obstacle? thank you.
BILL GATES: Sewage is a problem. Since it costs money to process it just gets dumped in slums in poor countries. The system the rich world uses of pumping in clean water and pumping it to a processing plant is too expensive. I challenged engineers to create a processor of sewage where the costs could be covered by the energy and water (clean water) that it outputs. We have made progress on that. One team, Janicki, which was written up in Wired, is send a prototype machine to Senegal later this year. Getting rid of sewage helps a lot to reduce disease and improve living conditions.
Speaking of the OmniProcessor. You inspired me to post a photo over in /r/photoshopbattles.
QUESTION: What is your opinion on bitcoins or cryptocurrency as a whole? Also do you own any yourself?
BILL GATES: Bitcoin is an exciting new technology. For our Foundation work we are doing digital currency to help the poor get banking services. We don't use bitcoin specifically for two reasons. One is that the poor shouldn't have a currency whose value goes up and down a lot compared to their local currency. Second is that if a mistake is made in who you pay then you need to be able to reverse it so anonymity wouldn't work.
Overall financial transactions will get cheaper using the work we do and Bitcoin related approaches.
Making sure that it doesn’t help terrorists is a challenge with all new technology.
QUESTION: One of the themes in this year’s Gates Letter is helping to improve agricultural practices in Africa. As a person who was raised in an agricultural community in Canada, the ideas presented really resonated with me. As an individual, is there anything we can do to help Africa achieve food security?
BILL GATES: Government aid funding from rich countries to develop new seeds and help the countries educate their farmers and provide credit to them can make a huge difference. Canada does some of this like the United States. We need to raise African productivity by 1.5 to 2x in order for them to avoid malnutrition and be able to lift themselves out of poverty. It is strange a continent with 70% adults as farmers imports food from countries like the US with 2% farmers. Africa spends $50B net buying food today. With productivity improvement they can offset the weather getting worse and feed their children enough to thrive.

QUESTION: Hello, Bill. As for the Reddit’s Secret Santa we know what present you’ve given this year. But we don’t know what gift YOU have received from your Secret Santa. Can you tell us?
BILL GATES: It is quite a coincidence but my gift arrived this morning. I got three cool things - a great quilt that a group of people did with a Snoo on it. A great jug of maple syrup and the book The Promise of a Pencil. All very thoughtful. Last year I waited and nothing came.
Edit: Reddit just let me know that I did get a gift last year: a generous donation to Heifer International, a great non-profit that helps fight poverty and hunger around the world. So, thank you /u/SailorKingCobra, my Secret Santa!
QUESTION: As there are so many great philanthropic causes, how did you and Melinda decide on the causes that you wanted to put the majority of your effort?
BILL GATES: There are a lot of great causes. It is important not to be frozen trying to pick since it is important to specialize and really learn the area you are trying to help. We picked health inequity as our global thing and educational inequity as our national thing and most of our projects fit into these areas. Part of the beauty of philanthropy is the diversity of causes and approaches that get tried. It is far more risk oriented than government or private sector spending which makes it special when it is done right.
QUESTION: Hello Mr. Gates, I admire the work you’ve done to eradicate diseases such as polio from the world. What can we do as citizens to help keep these diseases gone for good?
BILL GATES: Polio eradication is a big focus for me. Our last case in Africa was 6 months ago and we are hoping no more show up. It takes over a year to be sure. We still have cases in Afghanistan and Pakistan. Until we get rid of it there it can spread back to other countries. Pakistan is starting to take this seriously including the army and the government. They need to do the same things that were done in Nigeria. The Taliban makes it very difficult. They have killed women going to vaccinate kids many times.
QUESTION: Hi Bill, my question: Is there anything in life that you regret doing or not doing?
BILL GATES: I feel pretty stupid that I don't know any foreign languages. I took Latin and Greek in High School and got A's and I guess it helps my vocabulary but I wish I knew French or Arabic or Chinese. I keep hoping to get time to study one of these - probably French because it is the easiest. I did Duolingo for awhile but didn't keep it up. Mark Zuckerberg amazingly learned Mandarin and did a Q&A with Chinese students - incredible.
QUESTION: Do you have a pet? If so what’s his/her name?
BILL GATES: We have two dogs. One is Oreo and the other is Nilla. I will say I spend less time with the dogs than the kids do but I really like them (when they are not barking at night and not eating things they are not supposed to and when they are well house trained). I have resisted getting a third dog.
QUESTION: Mr Gates, Do you feel that we are facing an overpopulation problem on this planet? If so, what do you think needs to be done about it?
BILL GATES: Fortunately as people get healthy they choose to have less kids. We have already had the maximum number of births - that number is starting to go down. We still need to help provide health and contraception in poor countries but all of the global population growth is coming from people living longer. Hans Rosling talks about this in the clearest way.
QUESTION: In your opinion, has technology made the masses less intelligent?
BILL GATES: Technology is not making people less intelligent. If you just look at the complexity people like in Entertainment you can see a big change over my lifetime. Technology is letting people get their questions answered better so they stay more curious. It makes it easier to know a lot of topics which turns out to be pretty important to contribute to solving complex problems.
QUESTION: What do you think has improved life the most in poor countries in the last 5 years?
BILL GATES: Vaccines make the top of the list. Being able to grow up healthy is the most basic thing. So many kids get infectious diseases and don't develop mentally and physically. I was in Berlin yesterday helping raise $7.5B for vaccines for kids in poor countries. We barely made it but we did which is so exciting to me!
QUESTION: Hi Mr. Gates! Thanks so much for coming back again, I missed your last 2 AMAs. What do you think is the hardest challenge that the Bill and Melinda Gates foundation is currently facing?
BILL GATES: We have some tough scientific challenges like an HIV cure.
However the toughest thing is helping teachers learn from the best teachers. There are great teachers and the kids who get them are lucky. We should be able to spread those skills but the current system doesn't do it very well.
QUESTION: Mr. Bill Gates, what is your favorite expensive food?
BILL GATES: Nathan Myhrvold has some amazing modern cuisine stuff that is super tasty. I am not a foodie but his new concoctions are amazing.
I also like Thai and Indian food but it doesn't have to be expensive.
QUESTION: Thanks for doing the AMA. I am a great admirer of your philanthropic work. My question for you is regarding medical research funding. I know your foundation focuses largely on global health issues, but do you have thoughts on research back here in the USA? Governmental funding is reaching dangerously low levels, and many bright and talented clinicians and scientists aren’t even applying for federal grants knowing they have little chance of being funded. What can we do about this? As an aside, I am about to launch a non-profit dedicated to crowdfunding individual medical research projects. I’m working with little entrepreneurial experience or backing but a ton of passion and experience in the healthcare field—do you have any suggestions or is there anyone at your foundation who might take a few minutes to offer some advice? Edit: whoops. Reddit ate the end of my post.
BILL GATES: Research is very underfunded compared to the ideal. Society captures so much benefit from innovation that inventors don't so there is not enough risk taking. Government (and Foundation) funding of research helps but it still should be more. The United States funds a lot more than any other country even relative to its success. It should do more medical and energy and educational and other research. Politicians often think short term unless the voters tell them to avoid that. Perhaps the most outrageous thing is we have not raised Energy research funding to help solve climate change!
QUESTION: Although you are a billionaire, do you sometimes buy generic products over brand-name ones? If so, what are the products you buy?
BILL GATES: I am pretty basic when it comes to clothes and food. My big splurge is having a plane to fly around in.
I play tennis so I invest in shoes and racquets to help but they don’t make a big difference.
