It's a very good invention n I think it'll help us deal with meals especially when we're super busy or, like what you've said, on the go.
But what I can see is that in the future, all "food" will be in the form of liquids or even gases since ppl r too busy to care about cooking n relaxing by eating food. We'll forget what texture is like, n the art of cooking will be soon eliminated. Also, as mentioned in the vid, some may miss the perfect time for relaxing n may lead to mental problems.
In terms of evolution, teeth won't be needed anymore, so in the future human beings might have no teeth at all O_O Also our body may be too used to digesting such simple form of substances that our stomach no longer needs to churn food or mix them with gastric juice. Our stomach may not secrete gastric juice anymore, n may lead to problems in the immune system. Same goes for the saliva cause it's no longer needed to neutralize the gastric acids.
