ELI5: Synthetic meat

Does anyone know what has happened to the synthetic meat we were all promised many years ago that would be just as good as the real thing (One step closer to Blade Runner ). It's now 2018 I haven't seen one synthetic burger.  
and is it really that good for you... or not ?

No one has figured out how to make it cheap enough yet.  Consider the price of ground beef, if you have a multimillion dollar lab making lab-grown beef then you're going to need to make millions of pounds to have it pay for itself.

There are a bunch of companies work on it, but none of their products are commercially viable yet.
