I've been seeing these types of articles at the very least since the start of this decade. Here's one from 8 years ago, and there is at least some overlap in the comments. https://news.ycombinator.com/item?id=2951733 https://news.ycombinator.com/item?id=2951733 Not that there isn't progress. There certainly is. You can now buy actual products (albeit quite overpriced, considering the average American can't really afford to spend 200% of their food budget on a whim). However, it's important to keep in mind how much meat people eat, especially in the States. I think the average consumption is somewhere in the neighborhood of 200 lb/year. Here's a graph from 2012 https://www.npr.org/news/graphics/2012/06/gr-meatcomsuptionpercapita-462.gif https://www.npr.org/news/graphics/2012/06/gr-meatcomsuptionp... Let's set a reasonable goal of 10% of that being converted to lab grown meat. We'd need 5 billion pounds (10% of 2012 level) of lab produced meat every year. How close are we to that amount of commercial production? How much more efficient is it in terms of fossil fuel use? 50%? 75%? It's a great initiative, but simply reducing the amount of meat we eat (imagine having 1 meat-free day/week) is likely to be more effective than this, at least in the near future.
