Thinking back over the last 20 years I am not sure things have really changed that significantly so i wonder if they will actually change that much in the next 20.
Sure cars have got faster, stronger and relatively cheaper but if we take electric off road as an example then we are still typically qualifying over four 5 minutes qualifiers to stake a claim in a 10 car final as we did 20 years ago.
Battery, motor and esc technology has moved on and things like 2.4g radios and personal PT have made racing easier but they have not fundementally changed what do.
Just realised I raced my first electric off road buggy at a club about 35 years ago and on Sunday (weather permitting) I will be racing at that same club albeit with a couple of name changes along the way. The basis format of the day will be exactly the same. One thing though is they say practice makes perfect, they are wrong, I am still not going to win
