I'm not going to debate the word being used, but there are pretty significant differences from a technology perspective.
40 years ago most planes were nitro instead of electric.
40 years ago most planes required a builder willing to spend a few hours to a few weeks building a plane.
40 years ago zero planes had GPS.
40 years ago zero planes had gyro stabalization.
40 years ago zero planes had FPV.
40 years ago zero planes had auto pilots.
All of those advancements that have taken place in the past 40 years, mostly in the last 5-10, make a huge difference in terms of the cost of entry and accessibility in RC flying. You no longer have to be passionate and interested, you just have to have $500, a willingness to type your credit card into Amazon.com and you've got a plane that you can fly... That's game changing in terms of the people what will be flying them.
