The screen is the biggest consumer imho. I mean of course I understand that the phone can be removed by the suction mount, but thus also defeats the idle infotainment concept. Also seen screen burn in...

There's an awful lot of negativity here, but as someone who's 55 and has earned a good wage since I was 17, I really wish I had taken investing more seriously from the very beginning. While I knew of compound interest, I really didn't understand it until like a decade ago. If I'd started putting 5% of my money into a target retirement plan from 17, I'd be retired now. As it is I'm not doing badly, but I really wish I…

You say that now but as a young person with a decent income and no family or many responsibilities it's hard to even know where to start. And I'm not even talking about what to invest in, I'm already confused at which platform/bank/whatever to do it through. The "meta", if you will. I just want to invest the 70% of my salary I don't need every month and not think about it for 40 years but how? Maybe an important deta…

My understanding is that, if the market generally continues on the rate of return it's averaged throughout its history (that is, if you're not a doomer), then the single most important thing is showing up to play.

People who try to time the market or wait for a perfect time or pick the exact right blend of stocks, on average, don't do as well as people who pick a boring index or mutual fund and forget about it for 40 years.

Don't know about Switzerland, but most US brokers offer some kind of "target retirement date" fund, which automatically shifts from higher-risk assets to lower-risk as you approach retirement. VFIFX is one from Vanguard, for example. Pick one you like (just ask a coworker what they use, if you pick a big-name brokerage it really doesn't matter which one), shove your extra cash into it regularly, and forget about it.…

Even when it crashes it's like 20% no? It's not actually that big of a deal.

Crashes can be a lot bigger than just 20%.

I had a very similar idea this summer. But my kids are 6 and 8, so I approached it using the video game approach. It's been an absolute smash hit and entirely altered the habits of doing chores in this home. It's been about 3 months and it's still going stronger than ever. The whole thing is a static page, driven by a Google Spreadsheet that Mom and I edit to adjust goals and track progress. https://ibb.co/RTw5sCDJ h…

great!, mobile app?

It’s just a static hosted page they run on the family iPad. There’s no server at all!

I should really clean it up and make a blog post about it. But wanted to share it here because this project reminded me of it :)

I don't know what you mean by that. They teach compound interest in every school. Basic economics too. Anything more advanced is going to be lost on most kids, because that's most adults' level of financial literacy too. The problem is many kids don't have much money to save or invest. Or if they do, real banks kinda suck when you only have a kid amount of money ("Here's the 0.2% interest on your $37 balance"). So th…

While I certainly had the _concept_ of compound interest taught to me at some abstract mathematical level, the application to real life practical financial scenarios was definitely not done [1]. Economics as a whole was an optional subject. I think schools and curriculums could do a whole lot better in representing this important facet of life. More broadly, I often feel that "applying all that math you've learned to…

> the application to real life practical financial scenarios was definitely not done

Of course it was. You can't teach compound interest without referring to money or banks. That's the whole point of it. Otherwise it's just multiplication.

Hi, sorry to be that guys, I just wanted to make some corrections on what you call your app a "plain html file". Your HTML file loads: - react app - pwa manifest - tailwind css This is not at all a "plain html" file.

is plain html different from single HTML? Because it is a single HTML that you can "Save as" and have one html with the working app.

I have a "plain Python file" that only imports TensorFlow.

There’s an old story about Rothschild getting a haircut when the barber started giving him stock tips. Rothschild thanked him, left the shop, and immediately sold all his holdings. The reason was: “When even the barber is investing, the market’s gone too far.” I might be wrong, but reading this, I couldn’t help but think: if we’ve reached the point where we’re building apps to get our kids into investing, maybe we’re…

In December 2017 I literally saw shopkeepers and barbers checking Coinbase every few minutes when they weren't with customers. I sold a substantial portion shortly afterwards. Of course I'd be much richer today if I hadn't done that. But I don't really regret it because it's not real investing; it's speculation.

Incredible HN post. I'm hoping it's because you are from a country where people are generally well taken care of. Yes, there are people who don't invest. Where do they keep their retirement savings? 40-50% of Americans, at least, simply have no retirement savings! Most people in America aren't earning enough to put away a meaningful amount for retirement. It's going to be grim as boomers and millennials hit retiremen…

And it doesn't occur to them that they will need money when they're old and can't work? Incredible.

I am very certain it does occur to them but they simply have no financial means to do anything about it. Which must be soul-crushing to them.

Rest assured it usually isn't their choice.

It is one of the most common reasons people invest though so it's entirely relevant

I don't think you need a reason to invest. You should be making more money than you spend, so you might as well put the surplus to work.

Okay

Greed is at a 21st century high. I am just waiting for the rugpull moment when billionaires decide the show is over ( https://seekingalpha.com/news/4464647-deeper-dive-the-wealth... ). Even George Hotz understands this is the symptom of a larger issue and it is going to end bad: https://geohot.github.io/blog/jekyll/update/2025/10/24/gambl...

What is going to happen specifically when billionaires decide the show is over?
