Everything man-made will fail.
However generally, the more simple the motor, the less likely for a failure
My first car was a 1961 Ford - inline 6 and 3 on the tree. No air, no radio, drum brakes all around, points, plugs, crank windows, yada, yada. When you opened the hood there was a little motor and nothing else. Could not get any simpler.
Now 57 years later I still own a Ford product, yet when you open the hood it takes a few minutes to even find the freaking dipstick.
The '61 was a pita. The choke had to be adjusted for Winter, then back again for Summer. Brakes and tires were needed way too often. Tune-ups were annual, and it still never ran right. Constantly tinkering.
OTOH the 2018 is a marvel of Engineering and everything works perfect. I'm sure it will break eventually, but in the meantime I'm enjoying it.
I'm using this as an analogy for boats.
If you tell me you like old motors because new ones are too expensive, I can buy that. Also, I assume you fix them yourself because mechanics are few and far between.
If you tell me you like old ones because they are more reliable, I don't agree.
Nevertheless, what's so good about America is that we all have our likes and dislikes and we have the ability to do whatever we want.
