Another example of an old but solid rule of journalism, that if a headline contains a question mark, the answer will be “no”.

There would have to be an infinite number of vowels.

There’s also the glum opinion of Douglas Adams as expressed in The Hitchhiker’s Guide to the Galaxy, that if total mutual comprehension were to become miraculously available, so that everybody knew what everybody else really thought and intended, total intergalactic warfare would instantly ensue.

Such a system would make reading much more difficult. Imagine a world where the differences in British and American spellings weren’t limited to and extra “u” here and there and “re” instead of “er.” Instead, many words would have ten or more different spellings depending on the accent of the writer. Yes, you could decipher it, but it would be a plodding effort. It would be a total mess.

...and that’s before we get to the huge range of pronunciations just within this sceptred isle.
