Which branch of future tech are you most excited (or nervous) about?

AI is already writing emails, diagnosing illnesses and arguing with you on Twitter. Brilliant assistant or future overlord?

Scientists can now rewrite DNA like a dodgy Word document. It could cure inherited illnesses, but designer babies feel a bit dystopian.

Computers that can crunch problems classical machines would take millennia to solve. Nobody really understands it, including the people building it.

Limitless clean energy from squashing atoms together, like the sun does. Always twenty years away, but maybe this time it's serious.

Chips implanted in your skull to control gadgets by thought alone. Marvellous for paralysed patients, slightly terrifying for the rest of us.
