The machine is only as smart as the operator. The best engineering will never save an idiot from them selves. Besides, an idiot missing a few fingers is less dangerous…
As for the machine, it is fantastic. For commercial use this technology will be the standard IMO. As soon as someone gets hurt enough on a conventional saw to get the lawyers involved and they realize there is a “safer” technology available, well $$$. As for residential use, I see no use in the near future for it. The cost of the machine and the cost of repair once the device is activated (by a moth cocoon, small piece of buried metal, high mineral/salt wood like cedar) will limit its’ residential market. The machine does have a bypass for questionable material.
If I was seriously looking to buy this machine I would ask to see some life data. For example the device stilled worked flawlessly after 6,000hr especially in a commercial setting.
Bottom line – run the equipment you are comfortable using. There is no perfect tool.
BTW – there is no simple question.
