Capitalism here, why is 4) a con?

From your comment I assume you are American, since I heard that people pack your bags at your stores. In Germany and probably most of Europe a typical checkout process works differently and probably solves the problem.

1. You put your stuff on a large transport band, emptying your cart (probably have those as well)
2. When you're up you move your cart at the large area after the cashier
3. The cashier registers everything and pushes it to you into that big area
4. You put everything in your bags while they are working
5. Cashier finishes, you make your payment
6. You pack the last 3 items that are remaining

Some stores also introduced a simple "switch" that makes the products of the person after you slide into a seperate area, to save time .

There are always people getting annoyed by changes, doesn't matter what the changes are. Sometimes I get the impression that humans just need something to be annoyed about.

Not from the us but scientific research is usually very costly . They need funding to stay at the technological edge and therefore accept funding and therefore do some "shady" studies or whatever strings you might imagine.

Thats a Snog

Just leaving a "Aber die Spaltmaße" comment here.

Tu stulidus et asinus est.

Gotta learn the most important words first.

But also the deciders in the dev studios, that take the money even if it doesn't fit or don't integrate it properly.

I don't mind a little ad in the menu, about stuff directly related to game I'm playing. Those little "Hey we released a new content dlc to this exact game" infos can actually be informative. What I really can't stand is stuff breaking the immersion of the game. I'm not even mad about product placements, when they fit the theme and are sparsely used.

Your focusshould be on something that catches his interest. Depending on the child I'd say choose stuff that is easily to learn but has some depth too it. If you want to invest some time do some projects with him, to give easy goals to achieve and continue. Be the rabbit hole.
