I dislike having to enter my extremely long decryption password every time I boot. Also, I have no idea how your computer boots in seconds. POST to UEFI is at least 3-5 seconds. Than I have to wait about 5-10 ish seconds after I type my password to decrypt my drive. Than it gets to OS selection screen which takes 3-5 seconds. Then it has to load all services after boot which takes about another 5-10 seconds before things get into a vaguely usable state. This versus 2 seconds to wake.

10+10+5=35 seconds, not minutes. As i said, sleep was developed when boot took minutes. So the motivation for this feature has been greatly diminished and is now less of a priority in the linux community.

  I don't believe you. This is a community that recompiles kernels for imaginary performance increases. Who would forgo practical increases in speed. And when someone says "seconds" the implication is that its at max around 5-9 seconds. I would be pretty pissed if a application that took "seconds" to boot actually took 59 seconds.

    TBH I think the times of kernel recompiles with your personal settings are long gone. Folks these days just run Ubuntu/Fedora/<pick your distro> and that's it. Also probably most people don't have encrypted HDDs on their home computer, so another 10 seconds you can shave off. My current Ubuntu boots in maybe 10 secs from power button to login. And that includes the 3sec Grub menu pause.

  35 seconds is still kinda ridiculous when you consider the ludicrous speed of modern computers. If every cycle of a single core of a 3Ghz processor were a subjective second, then in that 35 seconds the core experiences a subjective 3327 years.

    Half of the 35 seconds in this case is from decrypting a drive and menu screens from having multiples OSs. Removing that and using fast boot BIOS options could easily drop this under 10 seconds.

      And time waiting for the wifi to reconnect. That is an entirely different wait cycle.

      Yes, my desktop usually boots in around 10 seconds. Or at least feels like 10 seconds; no more. In fact it takes more time for it to wake than to boot from full power off, albeit that says more about Linux sleep/wake support than anything else. But my point is that, for most of the time, I just leave it on. It consumes almost the same power sleeping that fully on, at idle.

      You say that like the decryption steps should be slow. The decryption is orders of magnitude faster than reading from the drive in the first place. And 10 seconds is still nearly 1000 subjective years. A Commodore 64 boots faster than the CRT can warm up and, while certainly doing less in the process, does it with a 1Mhz processor. Which, for reference, is 3000 times slower than our single core 3Ghz example not even accounting for CPI=>IPC inversion. Computers are ludicrously fast, but we've apparently worked hard as an industry to slow them down as much as possible even for the simplest of tasks.

        Seriously, why would you complain about this these days? In 2012, I was _impressed as hell_ when the SSD MacBook Air would fully boot OSX in 1 minute 30 seconds, being used to computers taking minutes to start and then spending even more minutes being unusable with the HDD thrashing like hell. These days my Linux desktop computer boots in around 10 seconds (much faster than either Windows or macOS on similar hardware, but at least on windows the boot time improvements have been incredible too). My desktop literally boots in less time than it takes for my DP monitor to power on from zero and start displaying frames. This is the wrong year to complain about boot time. I remember being on an airplane with no wifi and a brand new MacBook Air and spent most of the time idly turning it off and on, since I was really impressed :) . And today that > 1 minute boot time I would consider crap.
