Unlike these burgers, which aren't aiming to be healthier, LED lightbulbs aim (and succeed) at using less energy than their competition and thus contribute less to climate change. If the burgers both were healthier and similar to beef then they'd be like LED bulbs!
LED bulbs have the same effect (same brightness), while using 85% less energy. But in spite of that it's like still complaining that they run on fossil fuels as if that invalidates the efficiency gains.
Impossible burgers have the same effect (having a fatty, juicy burger) while ultimately being much less destructive to the environment. (They actually use something like 85% less water). But complaining about the fact that they aren't healthier is an attempt to take away from the other amazing advances involved.
I've had "lab-grown meat" (as I've called it) on my future-world wishlist for at least a decade. It seems like we could get rid of a host of problems (inefficiency, suffering, potential for bacteria and diseases like mad cow from meat, etc), by engineering our meat.
I suspect the health aspects will follow, as the next frontier, now that this stuff tastes close enough to meat, will be to reduce cholesterol and other effects.
After all, if you really think about it, 99% of the sensations related to eating food are before we swallow it. If we can replicate all those things (the touch, the smell, the taste, the sight) and start to engineer the internal effects, we could have our (artificial) cake and eat it too, correct?
I say this as someone who LOVES hamburgers, who is a big foodie. Apart from lack of food poisoning, there is fundamentally no difference in feeling in your stomach between fine dining food and a homemade sandwich. And the same goes for the effects on your health. So we should absolutely try to engineer these things for their effects on our bodies. But first you have to convince people to want to even put this stuff in their bodies. And that's what the appeal to the other 4 senses is.
You should {eat plants, use LEDs} because they use less energy.
