There are multiple FDA-approved lab-grown meats on the market. You can literally go to a handful of restaurants and order lab-grown meat today. The production process is just expensive and it's getting scaled out.

Lab-grown meat seems completely unrelated to synthetic biology. For lab grown meat the problem to my knowledge is that it is very expensive to grow vertebrate cells in the absence of an immune system because every contamination kills the batch.

let me put it this way .. it will come before the wallet gives out! (for masses)
