Lab grown meat.
Believe it or not, even stem cells need exercise in order to become edible meat. "To grow cells industrially requires a large ‘bioreactor’ – a high-tech vat that can provide the perfect conditions for growth but also the movement and stimulation to exercise the cells."
As 3d printers were 5 figures just 15 years ago, we may expect the same to happen to bioreactors; and meat printers may find their way to our homes soon. With that said, the bioreactor/spin bike combo is inevitable. So, here is one for you ;-)
