Expectations for safety have changed a lot,too. I raced ski team in high school. Helmets were optional and very few rec skiers wore them.

Now it seems unusual to see someone without one.

I’m aware of the haptic feedback the board is supposed to give when it is getting tired, though there are many claims of it not being produced prior to a nose dive.

Yes that product you linked is what I was describing. Note their description describes nose dives on the OW as “inevitable.”
