To me, the only old technologies that are "better" are things that we still use in a primitive manner. And even then, the newer versions don't work as well simply because the manufacturers are using cost cutting measures in the manufacturing process.
An old ax will have harder steel and a better handle than a new consumer grade ax. But that's not due to the lack of technology. That's due to manufacturers making an ax the average Joe can afford.
Then there is give and take. To me digital music technology is ten times better than vinyl. Why? Storage is tiny, cheap and limitless. Acquisition is cheap and limitless. Sound quality is great. Portability is tiny, cheap, and transferable.
Vinyl (or tape or whatever), to you, might "sound better". But storing the junk takes huge amounts of cubic footage, climate control, and shelving. You can't take the stereo, or even much of the music, with you without a huge hassle. If you damage the medium, it's all over unless you know how to splice tape or somehow regroove a record.
If you decide you want a live Miles Davis album I can have it downloaded and be listening to it before you find you car keys to go to the record store or find the album on Ebay. And if I don't lime it I can simply delete it and try something else.
I have 140 songs on my phone. Through the same account I can listen to any if them on any of millions of devices simply by logging into my account. I can delete and add all I want for 10 bucks a month. If my phone gets hit by an asteroid tomorrow I can get my songs back in another phone for free...other than the flat 10 bucks a month.
So, "better" is subjective. The get off my lawn crowd thinks I'm nut and thay there's "nothing better" than an old vinyl record run through a bazillion dollar tube mono block. I say "meh". Give me some ear buds or Bluetooth speaker or line into my stereo or Bluetooth to my car stereo or any number of other convenient options every time. Heck, I even run my phone into a powered mixer for learning songs in my jam room.
AM radio sounds horrible. I'm a ham radio guy and hear all kinds of varying quality radio signals. AM stinks for anything other than spoken word.
Old engines were OK to tinker with, I guess. But your attachment to them is romantic. They aren't "better". Modern engines work fine. You can do zero to them other than change the oil for over 100,000 miles. That was never true for any older car I ever owned. If something goes wrong with a new engine the mechanic can literally get a readout to a computer telling what's wrong.
I like old stuff too. But it's not "better". It's just old stuff I like.
