That's not what an Economist does. They can tell you that a specific policy is likely to have an impact along one or two dimensions (e.g. interest rate), but they don't know what policymakers at home or abroad are going to do, e.g. Trump's trade wars, or impacts of innovations across industries, e.g. AI leading to RAM shortage and data centres.

It's childish to pretend like Economists are supposed to anticipate everyone's every move in order for their work to be given credence. If you think tariffs are bad for consumers, an Economists worked that out for you.
