Not mentioned in the article: the market which this person was trying to enter is saturated with competition. These tour operators are bombarded with pitches for these things every day, and of course every one of them wants a cut of their hard earned revenue. It's a bad deal for a small business owner. They take all the risk, invest all the capital, while some SV firm comes along and kindly offers to scoop all the cream (margin) off the top.

So, this business failed due to a combination of lack of knowledge of the market and were not addressing a truly burning need for customers.

Hats off to the engineers who pulled this off.

But if you’re vaccinated, a Covid infection is still uncommon, and those high viral loads are not as worrisome as they initially sounded.

How small are the chances of the average vaccinated American contracting Covid? Probably about one in 5,000 per day, and even lower for people who take precautions or live in a highly vaccinated community.”

Amazon's co-mingling of inventory facilitated large-scale theft by enabling stolen goods to be sold along-side legitimately sourced items. One has to wonder: at what point does Amazon's reluctance to improve supply-chain integrity venture into the territory of aiding and abetting crime?

Has anyone found similar good-quality mathematics videos for young (elementary school age) kids?

This feature is a big plus for parents. It's hard to appreciate how hard it is to protect kids online if you don't have kids yourself. I get that those without kids will find it intrusive, but it sounds like these feature are opt-in.

I consider iOS to be the best platform for kids today. That said, Apple: if you're listening: please tighten up parental controls around time limits and re-loading apps!
