People are baffled over this machine that sorts out green tomatoes in a mere second
The automated sorter technology is fascinating, as is watching it work in slow motion.
An automated green tomato sorting machine is mesmerizing in slow motion.
For thousands of years, people around the world have been honing the art of agriculture. For the vast majority of human history, people planted and harvested and sorted produce largely by hand, gradually developing tools and machines over time that would make farming more efficient.
Many crops still have to be harvested and/or sorted by hand, but thanks to a rather mind-blowing machine, tomatoes aren't one of them. A machine that harvests tomatoes saves a ton of time and labor, but as tomatoes don't all ripen at the same time, pulling up an entire tomato plant results in a good number of green ones getting into the mix.
One solution to this problem would be to have the tomatoes transported down a conveyor belt in a factory while workers spot and remove the green ones by hand. However, an automated green tomato sorter does it right in the field as the tomatoes are being harvested, and a whole lot faster than any person ever could.
How many humans would it take to separate 32 green tomatoes from red ones in a single second? Um, a lot.
We'll get to the technology of how it works in a minute, but first you have to see the sorter work in slow motion. The machine is so fast you can't even really see what it's doing until you slow it down, but when you do, the wow factor is awesome. There are occasional misses, of course, but for how fast it's going, the accuracy is remarkable—and impressive to watch.
As James Vincent put it in The Verge, "It’s sorting tomatoes, but it looks like the fingers of God flicking damned souls straight into hell." Check this out:

So many immediate questions:
What?!?
How?!?
How does it know which tomatoes are green?
How does it work so precisely and freakishly fast to flick them away?
Am I the only one with a sudden urge to play Fruit Ninja?
The Henry Ford's Innovation Nation dove into a few of those questions with Don Douglas, president of Weco, a company that builds the optical technology behind the sorter. Douglas explained that light is used to create a reflection off the tomatoes and a sensor connected to software determines which tomatoes are green using that reflection.
It's actually tech that's been used for decades, but it's obviously been perfected and optimized over the years. Watch the machine at work and hear Douglas explain how it does what it does:
It's not always better to have machines do work humans can do, and there's certainly plenty of reason to be concerned about human labor being replaced by machines. But when that labor is back-breaking and tedious, technology can be a big help. Some inventions are also such prime examples of human innovation and ingenuity, you just have to marvel at them—even if they're just sorting green tomatoes from red ones.

Thank goodness this story has a happy ending.
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
