If all you wanted is to open a tomato can to cook your meal, and you end up opening all the cans, and not cooking your meal, plus now the can opener company knows:
- the meal you wanted to cook.
- the type of can you have at home.
- how many cans you opened.
- time of the day .. and really any data they can.
And now they can target you specifically with Ads that are tailored to you, so you can use the can opener as much as possible, no matter if you cook your meal or not.
Then yes, the designers should add friction, IF their goal is to live in a world where people get to cook their meals.
Is like the typical thing that happens when someone enters Facebook with one goal in mind, to check on something, and suddenly 45 minutes passed and they don't remember why you came on the first place.
If you use your can opener for an hour a day for a year, you have just about spent as much time as one of my friends spends playing League of Legends in a few months.
Should designers make can openers that are a pain in the back so people hate it to use them?
