That's we've been led to believe. The reality is however a bit different.

(But, seriously, Turing did not invent a universal machine. He invented a universal computing machine. Not the same thing. Yes, computers are very good at different computing tasks. But they are not as good at things that are not computing tasks. Like taking good pictures. Only part of it is about number crunching, the other parts such as good optics are still in another domain.)
