idk if anyone needs to know this but older things aren't better in 95% of cases. Talking about built/constructed things here. In some cases there are benefits to older techniques but for the most part the stuff built using newer technologies is head and shoulders over the old stuff. Some examples:
1) Houses -- recent construction techniques, insulation standards, electrical standards, plumbing standards, materials (house wraps, ZIP panels, etc) just make it so much better at keeping the inside dry and warm/cool (depending on season). The "sticks and paper" approach that you so often hear criticized about US houses is just dumb. A 2x4 wall at 16" on center is incredibly strong, way stronger than it needs to be. The new growth wood is just fine. I have a house built in the 1950's. I have taken 4 of the rooms down to the studs to redo the plumbing and electrical. In several cases the framing needed correction as well. There were several pieces with large knots. In one case this caused the ceiling to droop about 2" in the middle of the room as the ceiling joist buckled partially where the knot occurred. Several wall studs have been so heavily bowed that they required replacement. The old wood is not "better" because of closely spaced growth rings or whatever misleading videos tell you about it. Modern construction lumber is tested and graded to certain standards. Maybe the old stuff is 20% stronger on average, but with much higher deviation? But it hardly matters when the construction techniques result in a structure where each stud is 500% stronger than it needs to be, in terms of how much weight it can hold before weakening. (Not even kidding! a SYP 2x4 stud can hold roughly 4000 lbs in vertical compression. Typical loads in real life scenarios are more like 300-500 lbs. Yes, they can bow or buckle, but correct engineering / construction techniques prevent this.) Drywall is an incredible material for preventing the spread of fire, and it's so cheap that its downsides don't even matter at all.
2) Optics -- lenses and cameras. I own some old cameras; a Zeiss lens from the old East German Jena factory, along with old Nikons, Canons, Minoltas, you name it. A modern lens will smoke it. Sure it might not be made out of heavy steel so it feels like a rock in your hand. But the fact is, modern tools and techniques to precision-grind lenses, create super-pure glass, create brilliant coatings-- just make it stupidly easy to create stupidly good lenses. Yes, the old lenses were good. But you're paying out the ass for them because they're collector's items. This goes for anything optical -- riflescopes and binoculars being another example. Yes, some of the older models were built like tanks and had acceptable optics. Sadly, they are no better optically than the $50 China specials you can get at Walmart. The men who built the lenses in Germany in the 1950's were brilliant engineers. They had to do everything on paper and by hand. Modern computer technology makes it dead simple to create an optimized optical formula and have it ground to a degree of precision and consistency that would have seemed magical back in the day.
3) Guitars. Yes the old Martins and Fenders and Gibsons were the originals. They're what the Beatles and Zeppelin actually played in those recordings. But for similar reasons to what I've stated above for the other items, modern guitars are simply far better. There was far more variance in construction. You could try 100 old Stratocasters and find 1 or 2 that "sang" and had the right combination of body, neck, bridge, pickups.... but 98 of them would be nothing to write home about. Yes they were all made in the USA. But the current cheap models from Mexico, Indonesia, even China... made using current CNC mills, current tolerance detection, etc... it's all so much better. And don't tell me the old ones had "soul"... they were mass-produced in factories, using the cheapest available materials and construction techniques, and sold to the public at the lowest price possible. The high prices of older instruments just reflects the smaller number of them and the inanities of the collectors' markets. There is nothing inherently better about them, as pure musical instruments. The value comes in the provenance, the history.
4) Tools. Again, just modern machining, CAD designs, injection molding, metallurgy, etc. have made most tools simply far better. A $200 made in China sliding compound miter saw is a far better and more useful saw than any professional woodworker had in the 1960's.
I hope you can see where I'm going with this. There are examples everywhere. Cars.... I personally won't drive on a public street, and certainly not on a highway, in any car made before 2000 or so. Death traps. Old cars are cool, and fun to drive for certain purposes, but as a means of daily transportation they are far inferior to just about anything post-2000. Guns? Sure I own several WWII-era rifles, but purely for collector value (although the Garand is sure fun to shoot). A modern rifle is far better as a pure shooter. Same with pistols.
Really, there is one root cause of this: the tools that we use to make things, have gotten so much better. The computer is one example. Engineering drawings that would have taken many hours by hand, now can be rendered and iterated in seconds. And CNC machines can turn those drawings into finished products, accurate to arbitrary tolerances, in metal or wood or plastic, within minutes. So just about anything mass-produced (this includes most houses and other buildings, although they're not produced on a factory line) are simply made to much higher standards than just about anything could have been 50 years ago.
