Technology

It's a rather bizarre argument, essentially saying "it's not the whole solution so it's not a solution at all"

The article dismisses lab grown meat because the technology might cost $450m to build one 10,000 metric ton per annum producing factory, claiming it won't work because of economies of scale. But they clearly have no understanding of economies of scale. There is economies of scale in the building of factories and reactor production too. One novel reactor is expensive and difficult to maintain, but a global chain of 100s of factories become much cheaper to build individually and maintain as you have a whole supply chain and supporting infrastructure built out.

A good example of this is Apple's Vision Pro. The 1st iteration of this technology will be prohibitively expensive for most people. But by starting production Apple is stimulating the building of factories and infrastructure to build all the component parts at scale. Version 2 will be cheaper per unit, as will Version 3. The production capacity will increase reducing cost, even if the components iteritively get more advanced and complex from generation to generation. It's an expensive proposition for investors up front, but the long term potential to scale up is what makes it so powerful.

A "bio-reactor" to make meat is the same - the more you build, the more you invest in the supporting infrastructure, the cheaper it gets. There will be a risk barrier to starting, but it's crazy to dismiss the whole thing based on the projected cost of the first industrial scale factory. This is similar to Fusion power; the ITER fusion reactor in France is crazily expensive but the idea is the lessons learnt and the build out of the supportive infrastructure is what will move Fusion from a lab experiement to a real world source of power.

The reality is there is no one single solution to climate change, it will by multiple different things happening together that will improve the climate situation. Lab Grown Meat will help reduce methane from animals, while renewable energy will reduce carbon dioxide emissions from fossil fuels, and Electric Vehicles with renewables will do the same and so on.
