Bill Gates has given further insight into his new role at Microsoft and his hopes for the company's new chief executive Satya Nadella, admitting there is "more to be done".
Responding to questions in a Reddit AMA (Ask Me Anything) Q&A session, the Microsoft founder, former chief executive and newly appointed technology advisor said there were a number of areas Microsoft needs to work on, but added that Nadella was capable of doing so.
"Satya is taking a fresh view of where Microsoft is – strengths and weaknesses," Gates said. "A new person gets to step back and change the focus in some ways. He is off to a great start."
In his new role – where he will spend a third of his time working with Microsoft's product teams – Gates revealed that he would be looking to further improve the company's cloud services.
"I am excited about how the cloud and new devices can help us communicate and collaborate in new ways," he said.
"The OS won't just be on one device and the information won't just be files – it will be your history including being able to review memories of things like kids growing up.
"I was thrilled Satya asked me to pitch in to make sure Microsoft is ambitious with its innovation. Even in Office there is a lot more than can be done. Office connected to the cloud has a lot of potential and we are off to a good start," he added. "Cloud Storage needs to be a lot richer though."
Gates said that machine learning was an area of technology that deserves more attention. "So-called deep learning, which started at Microsoft and is now being used by many researchers looks like a real advance. It has already made a big difference in video and audio recognition – more progress in the last three years than ever before."
Meanwhile, Gates took a balanced view on the US National Security Agency's PRISM spying campaign. News of the programme, which broke last June, sent shockwaves through the tech industry and firms have since pushed for greater transparency over the government data requests they receive.
"This is a complex issue. Privacy will be increasingly important as cameras and GPS sensors are gathering information to try and be helpful. We need to have trust in the way information is protected and gathered.
"There is a role for the government to try and stop crime and terrorism but it will have to be more open. I do think terrorism with biological or nuclear weapons is something we want to minimise the chance of."
Gates will continue to spend the remaining two thirds of his working time on his charity work for the Bill & Melinda Gates Foundation, which tackles problems in the third world including malaria, poverty and foreign aid.
