When the 'one country, two systems' agreement was introduced, in the circumstances of China and Hong Kong in 1997, technology was not at the forefront of communication and informing as it is today, or as it will be in 2047. The idea of 'one country, two systems' was first suggested by Deng Xiaoping for the reunification of China during the 1980s. So how can the passage of time since it was introduced, and the technology developed since then, affect how well 'one country' two systems' can work?
As Hong Kong has grown technologically under 'one country, two systems', China' s stance on censorship has not changed much. Because of Hong Kong's laws that allow freedom on the internet, censorship is not as much of an issue, beyond the usual unlicensed copyrighted works and other things. However, it is different in China, with internet censorship meaning that a lot of websites allowed in Hong Kong would be inaccessible in China. Another issue with this gap between uncensored Hong Kong and censored mainland China is that Hong Kong is accustomed to greater freedom of speech than China online. As China has influenced Hong Kong more and more, one of the worries is the censorship laws coming into Hong Kong. A noticeable example of this censorship being used in the context of the Hong Kong protests is on the online platform Blizzard, where players have been removed for talking about Hong Kong.
One Country Two Systems was introduced when online news wasn't the main way to receive news and learn information. However, as the Internet grew and developed as technology such as phones and computers did, the world became more reliant on online news websites to be able to see the news from everywhere, and know what is actually going on. This is the case of the news in most countries, excluding a few. Hong Kong, because of its 'high autonomy' allowed by China, has the same dependency on freedom of speech and freedom of use of the Internet as most of the world, while China has some highly controversial censorship laws. As 2047 grows nearer, Hong Kong and its rapid growth of technology development and gaming could easily be stunted by the reversion to Chinese law. When the original handover happened in 1997, Hong Kong was a lot more vital to the economy meaning that they let Hong Kong do what they wanted to boost their economy, indirectly boosting China's.
As 2047 grows nearer, the gap that needs to bridged by Hong Kong and China on censorship and technological freedom grows bigger. The population of Hong Kong doesn't want Chinese laws to be put in place, regardless of whether they are technological or not. We know this from the outrage that the proposed extradition law caused. Technological freedom is one of the things holding 'one country, two systems' back from being a working system, but it's not the most important.
