Specifically for many musical instruments, machine-made is out of the question. For example, violins - there's an enormous amount of money to be made, but the entire market is handmade (even the low-end ones are ultimately assembled by hand, at extremely low wages in China.)
The quality of handmade items has improved a lot. Partially of course, because machines have corned the lower end of almost all markets; so if you go to the trouble of making things by hand, it better be good.
It's not like a chopstick that has 1 size, where you can press a button on an industrial chain of machines and end up with 10,000 chopsticks from 1 log of wood.
High end clothing is generally machine precision with custom sizing not hand made. Hand made cloth is an interesting novelty, but rare.
Growing up, when there was a failure in a refrigerator, television, radio, PC XT clone, etc - it was 95% of the time a simple matter of identifying the component or logic element that has black soot on it, soldering in a new one, and continuing on. You could follow the circuit logic and reason about how the system operates, and then shoehorn in CMOS TTL gates to modify operation logic to your heart's content.
With all logic moved to PLCs, MCUs, or black box SBCs, with components shrunk to 0402 SMD packaging - this is not longer a practical option afforded to consumers. We now throw the entire unit out and buy another.
The 1970s-1990s were a magical time when teenagers could disassemble, and fix or tweak their family's vacuum cleaner or phonograph, setting the stage for an early interest and foundation in engineering.
And now, that's gone.
You can go and see it at one of the houses she lived in.
It looks terrible by modern standards - very poor and rough.
Industrial design and production create items with tolerances, precision, and (optionally) durability that are almost completely unimaginable if you're making things by hand.
The only items up to modern standards are suits of armour and later clockwork pieces.
If you're used to modern manufacturing they look professional. But every element was made by hand - literally hammered or pressed out - and the incredible precision in later jointed pieces is just jaw-dropping.
