Wheelbuilding is difficult
Bikes are complicated
steel bikes are springy, alu ones stiff, Ti ones compliant, carbon ones stiff and compliant
bike mags know anything about material science/engineering
you ‘need’ gears/suspension/particular ratios/whatever to ride this trail or conversely that riding without the aforementioned is fine for everyone.
You have to spend lots to get good quality/longevity
A better bike will make you a better rider
