When I think back, just a couple decades ago, no one was thinking about boobs exceeding maybe 3500cc; they probably all thought they would split wide open by 7000cc, yet here we are. Who imagined permanent expanding breast implants or even using tissue expanders to create enormous boobs 20 years ago? Ever watched tissue expanders stretch skin over weeks in burn patients? Has anyone else taken care of a woman who weighed over 850 pounds? I have; skin has an amazing ability to stretch and grow over time when uncomplicated by medical conditions like lymphedema. To reject anything out of hand without considering the plausibility is the antithesis of science and knowledge. Suggesting that there can be larger boobs tomorrow isn't fantasy, this is not only very possible, it is likely. To think that the science is done, that there will never be any further advancements in medical prosthesis, breast implants will forever be constructed in the same way with the same substances is archaic thinking brought to you from the same purveyors that are selling the flat earth theory.
In just the past generation, huge advancements have been made in breast implants; it wasn't til the 60s that silicone implants were developed rather than just injecting silicone under the skin, which was much better than the things used before then, like rubber, glass, and foam sponges. Perhaps, in the future, expanding implants may use semipermeable membranes with a designated expandable filler that uses the body's own serous fluid to expand, much like compacted foam does today, expanding gradually as the skin allows until reaching the selected volume. The modern day Chelsea but with a cutoff. There is already a company selling B-lite implants, made with silicone foam advertised to be 30% lighter. Advancements will continue, it would be comical to suggest that we have reached the pinnacle of enlightenment.
