There´s been very little development in the modern quality bicycle in the past 40 years
Thru-axles, dropper posts, tubeless tires, disc brakes, carbon fiber, electronic shifting, suspension, and 1X drivetrains are obvious evidence of "development." Or do these not meet some arbitrary and subjective criteria of yours?

Manufactured victimhood is so undignified. Thousands of riders don't have any of the "new stuff" you're talking about, and uncomplainingly get along just fine year after year on the older equipment they already own. You can do the same.
