Even pros have switched from blade irons to cavity-backed clubs in recent years, so there has been a sea change in irons. the big deal, though, always seems to be drivers.
Golfers can more ably switch because they're hitting a stationary ball, I think. If they had to do what we do, they'd be less likely to change. Driving a ball 300 vs 275 can be very helpful; hitting a forehand 80 feet vs 78=LOSER!
