What's the biggest change the world has seen in your lifetime?

[Arturo Bassick]

A real example... maybe sword-making?

Saw a blacksmith on TV not so long ago make a bill hook from scratch. It didnt even need sharpening to be used (though he did put an edge on it shortly after). It cant be much of a step to make a sword.

Super slim TVs and Monitors. Do you remember when having a 21" monitor meant you had to use a 10 foot table for the back of it. Also a tv larger than 42" took up half the lounge + dining room.

Yes you can make a sword, even a fancy looking ceremonial one, almost as easily as a billhook. But to make a Saxon or Samurai multilayered sword that will stay sharp and not snap like a twig is much harder.

I'll bite. Name one

The only thing I can think of which might qualify is violins whose technique in manufacture has taken a few steps backwards over the centuries. But we can still make them

As mentioned earlier. Saturn V and Concorde. Not to say we couldn't make them again, but we'd have to start from scratch.

Making a sword is easy - just as making a chair is easy. Making an amazing sword that is folded hundreds of times is very very hard.

I have tried DIY and I can assure you it isn't easy. At least, not a chair that's suitable for a 16 stone person to sit upon with confidence.

There are still artisan samurai sword makers in Japan making swords with thousands of folded layers

Whats wrong with starting from scratch, neither took any skill to build which we no longer have

Not sure we are quite as good at rubbing along with the Frogs to be fair.
