What do you think is this possible with this serious chip or are these just meaningless concerns?
Personally, I am not all concern nor alarmed with any latest development of Quantum Computing courtesy of Google, an American firm operating for many years using the latest technologies available and can be introducing many innovations in different industries. What I am more afraid can be a counterpart technology that may soon be introduced and unleashed to the whole world...because I am sure that would be totally disruptive and with China at helm we would know what it might be used for...and just like the chaos brought on by China's DeepSeek. In summary, anything coming from USA is not to be afraid of...but the same thing can never be said that of China. Just my personal opinion, anyhow.
You are right to some extent. In general, the fear is not of the technology itself, but of its misuse by some, as you mentioned now, the example of the Chinese AI application DeepSeek, which caused great disturbances in global companies and the stock market. There could also be misuse of this scary AI in the future since it is cheap and open source.
