They don't have to be miraculous. In the UK, Brexit has caused the supply of ultra-cheap East European fruit-picking labour to dry up. Fruit growers are consequently now investing in automating fruit-picking.

Automation is simply engineering; these problems don't require miraculous inventions. Anyone can build a machine to pick a strawberry. The trick is building one to a price-point, that can pick an entire polytunnel clean, without damaging the fruit too much. It's not innovation, it's just applying stuff we already know to solve practical problems.
