By the time we can do this on pigs, the ethical disaster of the fact that billions of people will have died preventable deaths will be at holocaust levels. The only ethical action is to do this well before it's possible, roughly at the point where the probability of it happening at some point in the future crosses the cost-benefit threshold. The idea that there is a less than 1-in-10000 chance that in 10,000 years we will be unable to run brains in simulation given over the last ~50y of development we've produced hardware literally nine orders of magnitude faster than that of the brain, done so in a mass-producible fashion, made unbelievable strides in neuroscience, discovered CRISPR and make synthetic biology, gone from AI-as-theory to computers that can talk, describe images, and synthesise photorealistic faces, gone from technology as niche to CPUs on plastic that cost literally a since cent... is frankly an blunt unwillingness to consider the issue.
