How many people in the bar have used the mechanical keyboard 50,000 times?

The reference value of "50 million" service life of cherry shaft is the service limit when problems begin to appear during the experiment, which means that 50 million is only a conservative estimate. If used properly, it will probably not break after 50 million times on the shaft. Just like the shelf life, expired food does not necessarily go bad, and food that has not expired does not necessarily go bad (otherwise the manufacturer will bear the responsibility).

But in fact, the life of mechanical keyboard shaft mainly depends on the damage of accident nature, such as breaking due to excessive force, short circuit due to water inflow and so on. Roughly speaking, if you play a game with a single key that needs to be pressed frequently, such as the "X" key of Dungeons and Warriors (assuming that the continuous firing is not turned on), the combat rate of the game is 60%, which means that it can support about 4,630 hours of use. If you play 8 hours a day (the fighting rate of 8 hours is 60%, which is the hypothetical limit, and of course it is normal for professional gamers to change keyboards frequently). And in this extreme case, only the shaft will be damaged, and most keyboards can be replaced. You only need to spend a little money to replace this shaft, and the keyboard can still be used as usual.

Therefore, it can be seen that there are very few keyboards that are really replaced because of the end of life, because even if the life is up, it is not necessarily scrapped, and there is no need to replace the keyboard. There are only two ways to use the mechanical keyboard. The first method is to replace it in advance if you are tired of playing or dirty. The second method is to replace the single shaft whose life has passed without replacing the keyboard.
