Also knowing that oysters are essentially water filters, it seems strange to "eat the filter". I cannot even fathom eating Gulf coast oysters...
Having fake alternatives is nice. However, like the recent topic of the robotic industrial farming weed sprayer, I think it is engineering effort directed to the wrong place.
The #1 problem with transitioning from an animal based diet to plant based is the misunderstanding of what plant based diets can be. Ask a traditional meat eater what a vegetarian meal looks like, and they probably envision taking their steak away from the plate and just leaving some broccoli and potatoes. Indeed that's not very enticing.
Good vegetarian meals are practically art in terms of their combinations of textures and flavors, not to mention colors. But they take a lot more skill to make, so people rarely encounter them.
Instead, everyone is busy trying to replicate meat without meat - namely to replace that steak that was taken off their plate with something that is close to it.
Until we reach scale with lab grown meat (which even then I have doubts about long term downsides), no fake meat replacement is really good. They are manufactured, which means there are extra ingredients (or quantities of) that are not good for you. I think the reason for all this effort is that this is business. Companies want to sell you a thing; but a well made vegetarian meal is really just good plant ingredients and skilled preparation. It's hard to package that into a box which can be sold in the grocery store.
