And the week after that

Scroll for five minutes on any feed in Dubai and you will meet several confident announcements.

Shops are finished. Everyone will buy everything online within a few years. Advertising is dead and only word of mouth matters now. This one change to the visa rules, the school system or the way people are paid will fix the whole thing.

Declarations like these are exciting because they skip the middle. They go straight from the present to the ending, with nothing awkward in between.

Some of them may even be right. But a proposal that deserves to be taken seriously can usually survive a few plain questions.

Suppose it happens: what comes the week after, and the month after that? Who fills the gap left behind, and what do they do on the first ordinary Monday?

What are the actual moving parts? Not the slogan, but the mechanism, the dull steps that have to work in the real world, with real people who are tired and busy and slightly suspicious of change.

And why would people respond the way the announcement assumes? What is it about their habits, their fears or their wallets that makes this outcome likely, beyond the speaker's certainty that it is?

None of these are hostile. They are the questions anyone would ask before rearranging their own kitchen, let alone a market or a city.

Someone with a real idea is usually glad to be asked, because they have thought about it and the answers make the case stronger.

When the person making the announcement brushes the questions aside, or answers with more volume instead of more detail, that tells you something too.

It is a good moment to wait.
