Fact or myth: the computer should not be worn out by frequent switching on and off? Hibernate system on SSD?

Hello Khabrovites!

There is an opinion (read on the Internet) that the computer should not be turned on and off often during the day. Like, if you need somewhere to move away from the computer for 15-30-60 minutes (conditionally), then it is better not to turn it off, because "it harms it, wears it out." But the desktop can eat electricity well in idle time and somehow there is no desire to leave it on when the system is idle.
What will the Habr experts say about this?

I understand that it is better to use hibernation for such cases ... if the system is on an HDD. And if the system is on an SSD drive, then hibernation in the system is recommended to be turned off.

And using the "Sleep" parameter does not really change anything, because ...

The very idea came from the fact that during power cycling, the HDD wears out and, to a much lesser extent, the capacitors in the power filtering circuits.
So if we exclude from consideration the HDD (it does not exist) and capacitors (there are now solid-state ones), there is no breakdown with cycling.
The idea that frequent hibernation can ruin an SSD is also outdated, modern SSDs will survive and be replaced sooner - simply because they will not hold enough data.
