Impacts are harmful to the human body.
Millions of ppl have hand problems due to impacts.
Some from typing
Some from mousing.
Some from texting on their phone with vibrate function enabled. (Vibrations are just repetitive impacts)
Some from playing video games with vibrate function on.
Some from using a Jackhammer.
Some from hammering nails the oldskool way.
Keep impacting your nerves and they eventually get mad at you and revolt and cause you bad problems.
You were warned.
yes bottoming out is just like seeing a jogger run to the doctor and go, "doctor doctor, i can't run anymore it hurts" doctor says "that's cuz you've pounded 1000000 miles into your bones, now you got not cartilage". DO NOT bottom out.
yeeeeah this is the kind of conventional wisdom which gets passed around forums and becomes unpopular to disagree with, but unfortunately doesn't have a basis in fact.
Impacts are harmful to the human body if you try to absorb them with structures which aren't meant for absorbing impacts. When your typing technique is correct, you can type as hard as you want (within reason) and it won't hurt you, because the impacts will be absorbed safely and harmlessly. Just as you believe bottoming out is harmful, some people believe that typing on a stiff keyboard (say, cherry blacks) is harmful as well. Note that pianists experience FAR stronger impacts at a much greater frequency, and are forced to exert far more force to play on the typical grand piano than is necessary to type on the typical mechanical keyboard. yet many concert pianists have life long careers with little to no physical difficulty.
Sure, many pianists do experience RSI. But not all. And if "impacts" or stiff keys truly were harmful to the human body, then every concert pianist in existence would have his career ruined by debilitating RSI. And this certainly is not the case.
Just as there are many runners all over the world who run daily for years and years and never experience harm from it.
It's not how hard you type, it's the manner in which you do it.
It's the same sort of thing that you see leads people to be so confused as to why their wrists still hurt when they're using a wrist rest. It's because they don't understand how the wrist is supposed to be used. A rest won't change that.
