I once bought a table saw, then watched a YouTube safety video about table saws, and then sold my table saw. I wouldn't even consider owning a lathe. I know my limits, and even the chop saw in the garage gives me the shivers.

I used a Craftsman radial arm saw for a while. One day, I rotated the head 90 degrees to do some ripping. The saw grabbed the wood, and climbed up on it, and fired it at unbelievable speed at the wall. It punched a neat hole in the wall the exact size of the board, and the board disappeared into the next room. I got rid of the saw after that, and bought a sweet Makita cutoff saw instead, and a table saw for ripping. I also bought one of those full face shields people use with chain saws. I like these better than the usual shields because they are a wire mesh, and screens don't fog up.

  For what it's worth the 3M full-face respirators are very well designed in that the inlet air passes over your face and then into a sub mask where it is inhaled. Exhaled air is directed out of the front and down. I spent hundreds of hours with one (the FF400) in unconditioned spaces running power tools in fairly strenuous ways and never had it fog at all.

If I ever need a table saw I'm getting one of the pricy ones that stops before it chews up your hand[1]. My cousin is a professional furniture maker and lost the tips of 3 fingers to a table saw. It happens quickly. [1] https://m.youtube.com/shorts/vCuLs31fDaQ https://m.youtube.com/shorts/vCuLs31fDaQ

  Wow that was fast, how does that safety system work?

    https://en.wikipedia.org/wiki/SawStop https://en.wikipedia.org/wiki/SawStop "An oscillator generates a 12-volt, 200-kilohertz (kHz) pulsed electrical signal, which is applied to a small plate on one side of the blade. The signal is transferred to the blade by capacitive coupling. A plate on the other side of the blade picks up the signal and sends it to a threshold detector. If a human contacts the blade, the signal will fall below the threshold. After signal loss for 25 micro seconds (µs), the detector will fire. A tooth on a 10-inch circular blade rotating at 4000 RPM will stay in contact with the approximate width of a fingertip for 100 µs. The 200-kHz signal will have up to 10 pulses during that time, and should be able to detect contact with just one tooth.[4] When the brake activates, a spring pushes an aluminum block into the blade. The block is normally held away from the blade by a wire, but during braking an electric current instantly melts the wire, similar to a fuse blowing."

  I have a Sawstop for my main cabinet saw in my shop at home, but also a regular job site saw for working elsewhere. The table saw is a great tool, and the safety feature makes sense. Especially for the cabinet saw where the incremental price for a comparable too is not so much - but there are plenty of other power tools that will hurt you just as badly. A router or jointer won't amputate a finger, it will just turn it to hamburger. No matter the tool, you need to respect it and learn the safety rules.
