I think Mr Baggini was basically saying to the plex ..show us a new trick within 4 years ..or we are gone ..and our money goes with us ..

From the way the quote was worded, I'd say that Mr. Baggini expects Google to have additional types of revenue in four years. (Note that he said "I'd be disappointed...", not "I'll be disappointed.") Of course, it's always possible that English isn't his first language or that he spent too much time studying finance at the expense of grammar. :-)
