I think we should engineer the perfume equivalent of a headphone: something plugged directly into the nostrils so that the smell doesn't offend too many people.
This is it, for a while battery life got worse for a while with more powerful chips. But then Samsung goes full in on the big size 6"+ phone and it got better again.
Now even at 80% original capacity, a Samsung can still last me throughout the day given that I am not watching videos constantly. The Iphone 6 back in the day would go to 40% in 3 hours, then suddenly to 5% in minutes.
Plus most people replace their laptop with a phone now. So the big screen size is a must.
Oh wow I forgot that the microwave oven was once marketed as the total replacement of cooking chores and in futuristic life people can just press a button and have a delicious good meal ( well you can now but microwave meals are often seen as worse than fastfood ).
