It's reasonable to have the opinion that juggling chainsaws is a dumb idea, even before you've learnt the techniques for making it slightly less dangerous.
Is that really any dumber than doing any similarly dangerous industrial jobs that require a lot of training? Or something else dangerous in entertainment like being a Hollywood stuntman, or being Siegfried & Roy? I'm sure you could get a lot of money for having that skill if you did it in the right place.
