This is a most excellent place for technology news and articles.
There are rumblings that all tablesaws will have to ship with something like that installed. It could make it illegal to sell your old tablesaws just like it's illegal to sell old lawn darts.
The patents are expiring and once they do regulators will kind of have their hand forced. Trying to mandate a solution only available through one provider is a nonstarter. And that's part of the darker side of Sawstop. He did try to have it mandated by law after companies didn't buy in. It was a very self serving move that made a lot of enemies.
