That confuses me when American people say it's a hundred degrees outside or something. By European standards a hundred degrees sounds insane.
#2
生徒 (とにお)
1/2Yes, a hundred is about 30 Celsius. And also the height, they use inches, like six foot tall. I'm Asian, a typical Asian, not tall, average, like 5 foot 8, 172 cm.
2/2It's very confusing, but I'm getting used to it, pounds and feet and Fahrenheit, because I consume English content, American content, daily. So they use that, like a triple digit hot day. I'm used to that now.
NATIVE俺の表現の修正chunk 1/1
A hundred Fahrenheit is about 30 Celsius. I'm pretty average height for an Asian guy, 5 foot 8, around 172 cm. I've gotten used to feet, pounds and Fahrenheit just from consuming American content every day.
ENGAGED本物の会話の深さchunk 1/1
The funny thing is I never sat down and learned Fahrenheit, it just leaked into my head from the content. American media installs its units in you before you notice. Did you ever actually learn miles, or did movies just do it to you?

1/2It's funny, this counts as English studying, but it's not really about English. It's about American stuff, cultural difference, people in different regions using different measures. You're British, so we share pretty much the same standards.
2/2Only the American guys use these weird ones. We have a point, right? Celsius and the metric system, that's the scientifically correct way.
NATIVE俺の表現の修正chunk 1/1
Here's the funny part: this counts as English study, but it isn't really about English, it's cultural knowledge. You're British, so we share the metric world; it's the Americans who are the outliers. Honestly, metric is just the more logical system.
ENGAGED本物の会話の深さchunk 1/1
Let me push back on my own smugness there. Metric is more consistent, sure, but a hundred degrees feeling hot isn't wrong, it's just human. Every system is somebody's normal, and 'correct' is mostly what you grew up with.

1/2For example the mile. I'm a baseball fan, and listening to MLB broadcasts and podcasts, they use miles, not kilometers. In Japan, 160 kilometers is the benchmark of a very very good fastball pitcher.
2/2In America, 100 miles is the benchmark, and 100 miles is almost exactly 160 kilometers, like 161. Different metrics, but pointing at the same result: if you throw 100 miles or 160 kilometers, you're very very good.
NATIVE俺の表現の修正chunk 1/1
Take baseball: MLB broadcasts measure pitches in miles per hour, not kilometers. In Japan 160 km/h marks an elite fastball; in the US it's 100 mph, and the two are almost the same number. Different units, identical meaning, that's a world-class arm.
ENGAGED本物の会話の深さchunk 1/1
What I love is both cultures picked a round magic number, 100 and 160, and they just happen to line up. The radar gun is objective, but the number you brag about is cultural. Does 100 just sound more heroic to you than 161?

TEACHER講師の native 表現chunk 1/2
In English we use miles as a reference, but don't they use kilometers when they drive in America? Oh, they use miles in the car as well? Interesting.
TEACHER講師の native 表現chunk 2/2
Britain is the outlier really, in most of the EU they use the metric system and drive on the right.
#6
生徒 (とにお)
Oh I see, I didn't know that. I thought you guys use kilometers when you drive, but you use miles when you drive. So it's very confusing, the same units used differently in different countries.
NATIVE俺の表現の修正chunk 1/1
I didn't realize Britain drives in miles too; I assumed the UK used kilometers on the road. It's confusing how each country mixes and matches its units.
ENGAGED本物の会話の深さchunk 1/1
So Britain keeps miles and drives on the left, basically the stubborn exception to its own continent. It makes me think keeping the old units isn't about logic, it's about identity. Is it pride, or does nobody just want to repaint every road sign?

講師
TEACHER講師の native 表現chunk 1/1
There's a really interesting story behind which side you drive on, going back to horses and carts and ancient Rome. After the French Revolution, Napoleon pushed driving on the right across Europe. And the British helped Japan build its railways when Japan was industrializing, so Japan adopted a lot of British conventions, then later picked up a lot of American ones too.

生徒 (とにお)
Yes, so it's very mixed and complicated, back and forth. I'm pretty surprised, you're very knowledgeable, you can explain all this historically. Maybe you are naturally reading some stuff, these interesting stories.
NATIVE俺の表現の修正chunk 1/1
It's all so mixed and tangled, back and forth. I'm impressed you can explain the history like that, you must be the type who naturally reads into this stuff.
ENGAGED本物の会話の深さchunk 1/1
Most people just accept 'we drive on the left' and never ask why; you chased it all the way back to Napoleon. That itch, needing to know the why, is rarer than it sounds. Where does yours come from, a teacher, a book, your dad?

1/2Can I tell you about my English journey? I'm not a guy studying English for some kind of goal, no exam, no changing my job. But I'm building my own English study app with AI, and I'm promoting it on X.
2/2I'm not casually using X, I have no interest in scrolling for three hours. I use it on purpose, for a specific reason, just to make money, simply put.
NATIVE俺の表現の修正chunk 1/1
I don't study English for a goal, no exam, no career move. But I'm building an English app with AI and promoting it on X. I don't scroll for fun; I use X purely as a business tool to make money.
ENGAGED本物の会話の深さchunk 1/1
Most people open X to kill time; I clock in like it's a shift. The trap is the app is engineered to turn my 'tool' back into a three-hour hole. How do you keep a slot machine from eating the person trying to use it?

1/3Starting from zero is very tough, zero followers, zero following. You tweet something but no response, obviously. So you follow big influencers and people on your level, near zero, and you do mutual follows, scratch each other's back.
2/3The numbers go up on both sides, but it's not a real relationship. It's like a bubble economy, it doesn't happen in the real economy. And they often unfollow you afterwards, just for the numbers.
3/3It's very sad.
NATIVE俺の表現の修正chunk 1/1
Starting at zero is brutal, you post and hear nothing. So people do mutual follows, scratching each other's backs to push the numbers up. But it's a bubble: no real relationship, and plenty unfollow you once they have their count.
ENGAGED本物の会話の深さchunk 1/1
Mutual follows are a fake economy, two people inflating each other's scoreboard. It's like two countries passing the same banknote back and forth and calling it GDP. Have you actually gained anything real, or just a bigger number?

1/2I had my AI research the X algorithm. It's open source, so you can access it. The answer is obvious: it's a point system.
2/2Some activities are favored, some are not. It's quite fair and open, so everybody is trying to exploit it the most effective way. At the end of the day your tweet has to be read, to pop up on other people's screens, that's the only method.
NATIVE俺の表現の修正chunk 1/1
I had my AI dig into the X algorithm; it's open source, so it's all there. It's basically a points system that rewards some actions and ignores others. It's fairly transparent, so everyone games it the same way.
ENGAGED本物の会話の深さchunk 1/1
Here's the trap with an open algorithm: the moment everyone can read the rules, gaming it becomes the baseline, not the edge. Fair and exploitable end up being the same thing. So does transparency actually help the little guy, or just teach everyone the same tricks?
#12
講師
TEACHER講師の native 表現chunk 1/1
Is it a fair system, or can you sort of hack it somehow? Is it just done on popularity, or do certain topics go higher?

生徒 (とにお)
1/2It's quite fair, a point system, open. But since Elon Musk took over, the blue check, the verified mark, you can just buy it, five bucks a month. It's genius of him, because there are a lot of egos on X showing off.
2/2And for promotion, if you're not blue checked, the algorithm doesn't favor you, you won't show up on other people's screens. So it's basically mandatory if you're using X for business.
NATIVE俺の表現の修正chunk 1/1
It's fairly transparent, but here's the catch: since Musk, the blue check is just five dollars a month, you simply buy it. It's genius, because X is full of egos happy to pay. And without it the algorithm barely shows your posts, so for business it's basically mandatory.
ENGAGED本物の会話の深さchunk 1/1
Musk turned status itself into a subscription, he's charging people rent on their own ego. The brilliance is it isn't really optional; he made invisibility the price of not paying. Do you resent paying it, or quietly respect the move?

1/2Can I tell you a funny, scary story? It happened yesterday. X has a boost mode, you pay to promote one specific tweet for a certain period, 24 hours, and you set your budget.
2/2I'm so new to X, and the funny thing is I didn't notice, I promoted one specific tweet without realizing it. I pushed the button two or three times and it started without me realizing.
NATIVE俺の表現の修正chunk 1/1
Here's a scary-funny one from yesterday. X has a boost mode: you pay to promote one tweet for, say, 24 hours on a set budget. I'm new, so I tapped the button a couple of times and started a paid campaign without realizing it.
ENGAGED本物の会話の深さchunk 1/1
That 'oops, I clicked it' is never really an accident; the button is built to be easy to press and hard to understand. The confusion is the product. Did it actually warn you it would charge, or did it just quietly start spending?
#15

TEACHER講師の native 表現chunk 1/1
Sometimes that can go viral, right? That could be quite a big achievement, quite valuable.

生徒 (とにお)
1/2I got a million views in 24 hours on that one tweet, but mostly fake accounts, just pushing the like button, 99% garbage. Still, some middle sized influencers retweeted it, so it kind of went viral. The problem is I didn't mean to pay.
2/2It ended up costing like 30 or 50 dollars. When I got up this morning and checked, I was so scared, what if it had been a thousand?
NATIVE俺の表現の修正chunk 1/1
That one tweet got a million views in a day, though most were junk, fake accounts just tapping like. A couple of mid-sized accounts retweeted it, so it half went viral. But I never meant to pay; it cost about 30 or 50 dollars, and I was terrified it could have been a thousand.
ENGAGED本物の会話の深さchunk 1/1
A million views and the thing you remember is the 50 dollars, that tells me you don't trust the views yet. Empty reach should scare you more than the bill, a number that looks like success but sells nothing. Did any of that million actually click through to your app?

But it turned out pretty good in the end, the hard way, but good results. Next time I'll show you, it was so funny, many crazy English guys in the replies.
NATIVE俺の表現の修正chunk 1/1
It worked out in the end, the hard way, but good results. Next time I'll show you; the replies were wild.
ENGAGED本物の会話の深さchunk 1/1
Learning by accidentally spending money is expensive, but it sticks, you'll never misread that button again. Honestly the 50 dollars bought you the lesson, not the views. Which did you need more?
