These skills are quietly disappearing, one day you’ll need one, and nobody will know what to do. read:
1. Writing in Cursive
Over 20 U.S. states no longer require cursive in schools. Most Gen Z students can barely read cursive, let alone write it. The art of elegant handwriting is fading into history.
2. Reading an Analogue Clock
Many classrooms have replaced wall clocks with digital ones. In surveys, teachers report that 1 in 3 students can't read time on an analogue clock in the US.
3. Using a Physical Map
Paper maps are nearly extinct. Studies show 90% of people rely entirely on GPS for navigation. We've traded our internal sense of direction for a robotic voice saying "Turn left."
4. Memorizing Phone Numbers
A study found 71% of people can't recall even their child's school number. Only 1 in 3 adults knows more than two phone numbers by heart.
5. Mental Math
Calculators killed quick thinking. In schools, the ability to do basic double-digit math mentally is dropping fast. Digital tools are replacing one of humanity's earliest problem-solving skills.
6. Driving Manual Cars
Manual transmissions are disappearing. In 2000, 86% of cars sold were manual now it's under 25%. A whole generation might never learn to shift gears.
7. Sewing & Clothing Repair
More than 77% of people don't know how to stitch on a button. Younger generations prefer to replace rather than repair. The needle and thread are losing their place in modern life.
8. Using Radios
Analog radios once connected the world. Now, less than 5% of new audio devices sold are non-digital. Tuning a radio station by ear is a forgotten ritual.
9. Reading Morse Code
Once vital for soldiers and sailors now, almost obsolete. Even in the military, Morse is no longer standard training. A 200-year-old language of dots and dashes has gone silent.
10. Reading Newspapers
Physical newspapers are vanishing. Over 70% of adults now consume news exclusively online. The morning paper, once a daily habit, is now nostalgia.
11. Writing Letters
The average person sends 0 handwritten letters per year. Emails and DMs have erased a 5000-year-old tradition. Even "love letters" are now typed and edited with emojis.
12. Navigating Without GPS
A study found people using GPS remember 30% fewer route details. Digital navigation weakens our spatial memory, literally reshaping the brain. We've become followers, not explorers.
13. Film Photography
Film sales dropped 97% since digital cameras took over. Few photographers today know how to load or develop a film roll. Capturing moments no longer feels like a craft, just a click.
14. Using a Compass
Most young hikers can't orient a map or find true north. Outdoor instructors report a 60% drop in compass-reading ability in under-30s. Nature hasn't changed, our instincts have.
15. Typing Without Auto-Correct
Before smartphones, people memorized spelling. Now, 1 in 4 young adults admit they can't spell common words unaided. Autocorrect made us fluent but forgetful.
16. Basic Home Repairs
From changing bulbs to unclogging drains. DIY confidence has dropped by nearly 50% since the 1990s. We've replaced problem-solving with service calls.
17. Handwriting in General
A Cambridge study found handwriting speed and legibility are declining. Students type faster than they write but retain less when doing so. We're trading memory for convenience.
18. Using Landline Phones
In 2004, 90% of homes had one.
Today, under 25% do. Future generations may never experience the "hang-up" click.
Which one of these skills do you still have, and which one should we bring back first?

I’m 54, a physicist, have spent decades using mathematics to study the universe, solve problems, and build things.
If your work touches numbers, now or in the future, and you want to learn math properly, this thread shows a from-the-ground-up math you’ll actually need:
I’m going to share a few everyday physics facts that will change how you see the world forever, so if you’re curious, read this:
1) You don’t actually “touch” anything.
→ What you feel as touch is electromagnetic repulsion between electrons, plus the Pauli exclusion principle preventing them from overlapping. It’s pushback, not atoms pressing together.
2) Solid objects are mostly empty space.
→ Atoms are like tiny solar systems: a minuscule nucleus with electrons around it. “Hardness” comes from forces and structure, not from being packed solid.
3) GPS only works because we correct for relativity.
→ Satellites move fast and sit higher in Earth’s gravity, so their clocks tick differently than clocks on the ground. Without corrections, the error grows quickly.
4) Your phone camera is basically counting photons.
→ The sensor turns incoming photons into electrons, an electrical signal. The image is a measurement of light, not a picture that already exists.
I’m a 54-year-old low-tech dinosaur. I can barely find the settings menu.
Still made $3,000 on X last month by posting about physics, cosmos stuff.
If you’re still young and want to build a side hustle on X, read this:
1. Start with the basics (eligibility) for at least 6 months. 2. Pick one lane first for at least 6 months. Ads rev share, subs, affiliates, sponsors. Choose one to learn before stacking the rest.
3. Post daily (or almost daily) for at least 6 months. Consistency beats “random genius once a week.” 4. Chase attention, but keep trust for at least 6 months. Viral gets views. Trust gets income.
I’m 54, a physicist who’s spent decades unraveling the universe’s secrets—from quantum quirks to cosmic scales.
If you’re in your 20s and passionate about physics or science, please read this:
1. Build your mathematical foundation early. Calculus, linear algebra, and differential equations are your tools—master them like a craftsman. 2. Experiment relentlessly. Theory is great, but hands-on labs teach you the chaos of real data. Start with simple setups at home.
3. Read classics first. Dive into Feynman, Einstein, or Newton’s originals before modern texts—they spark intuition. 4. Question everything. Science thrives on doubt; don’t accept “facts” without probing why.
