He probably noticed that you never let go of your wheel, or the times that you did the car veered off

It's probably the best way to spot if someone's not servicing their car regularly, considering wheel alignments are ultra cheap and are sometimes even done for free alongside a service.

Large scale companies have much more complex websites, have graphic designers, front end coders, back end programmers, UX designers to build the websites, and multiple of each role because there is a lot of changes being made, tests being run, issues being fixed. There are also IT people managing the servers or AWS/Azure environment, managing databases, cybersecurity, etc. and people who monitor sites, run analytics, and such.

Then there are tons of sales people/account reps working with companies to manage profiles and set up job listings, tons of support people screening job postings, providing customer service to job seekers.

Then there are the roles all companies have — marketing departments, accounting department, HR, legal, IT and such…

When I was in third grade I asked my teacher for some extravagance like an ice cream party. The teacher said "You'll get your ice cream party when pigs fly". My mom was also a teacher so I hung out around the school once the kids left.

I cooked up a plan with the head custodian which included drawing a pig with wings on paper twice, stapling the two pigs together with cotton balls stuffed inside and coloring it pink. Then Melvin and I hung the flying pig from a long piece of twine taped to the side, GOT ON THE ROOF OF THE BUILDING, and swung the pig back and forth in front of my teacher's window.

She correctly concluded that pigs had flown, our ice cream party was arranged and Melvin got the first bowl. He retired as a much loved member of the community and I get to remember that here was a time like 40 years ago when some adults would help kids do cool shit.

It’s called a hardy weinberg equilibrium. Unless there’s some catastrophic event, like we kill all the redheads, or something less sadistic like some kind of geographic change like a flood and a new River happening to divide people, random chance plus the continued passing of recessive genes keep things where they’re at.

We’re talking about absolutely massive sample sizes so it works out that you might end up reproducing with someone who has recessive genes you didn’t know about.

Honestly, I think the same as you. Maybe not 10 people, but even being generous, it would be below 500 people. The thing is, when these companies get funding, they start hiring more than they need.

So while before you had maybe 3 FE devs, now you have a whole team. Before you had only one Product Manager, now you have a “Product Owners Team”. Before you had 1 QA, then 1 QA per team, and now a whole QA team. And the same goes for marketing, UI/UX designers, and of course HR and accounting. Where the numbers really blow up out of proportion is IT and Marketing.

How does any business that operates machinery have so many employees? If your core business is machinery that stamps metal into widgets it does not follow that you need one guy to turn the machine on at 9am, then off at 5pm. You need to design them, you need to repair them, you need to update them, you need to clean them, you need humans to react every time something unpredictable happens. Then once you have more than a handful of employees, you need hr, bookkeeping, office maintenance, and management to coordinate all that.

Also, a business like indeed is going to employ a huge number of salespeople to sell listings and recruiters to try to fill them. Regardless of what you've heard, websites are not magic money machines that effortlessly operate at a profit once built. They are just a way of interacting with your human customers who still bring all the issues human customers bring.

A recessive gene doesn't mean it doesn't exist, just that it doesn't get presented. Someone can carry the gene without expressing it.

For example, if we have a parent with brown eyes, and let's say they have 2 copies of that dominant gene, we will call that BB, and a parent with blue eyes, they kust have 2 copies of that recessive gene we will call by. The child will have one of each copy, to they will have brown eyes, but will have the genes Bb. If they have a child with another person with Bb, then they each pass one copy on at random. We can get B from both, resulting in BB brown eyes, or B from 1 and b from the other, resulting in Bb brown eyes, or they could get blue eyes and have bb.

Recessive genes just mean it's less likely to be expressed, but it's just as likely to be passed on.

Dwarfism is a dominant gene, but it's not taking over the genepool. Although is mostly due to the fact that having two copies of the gene is fatal.

It wouldn’t necessarily die out even in that case, because there are lots of other factors than that predator involved in who survives and reproduces. There are going to be brown haired people who die for other reasons, and blonde haired people who aren’t killed by the predator.

Even if the recessive gene is always fatal if you get two copies of it, and the gene is the only factor in survival, it’s still going to take a long time for it to disappear, because humans take so long to get to reproductive age.
