Your entire statement was incorrect.
Glitches, exploits, and everything else are easy to find if you know where to look.
This assumes that glitches are present. To get CFW running you need to find a bug in the kernel or whatever is loading the kernel. Other consoles use monolotihic kernels so there is lots of room for error that can be exploited, the Switch is using a micro kernel so only the bare minimum amount of code needed is running. This means there is less room for glitches to slip in, and means that it is easier to reverse engineer. Since it is easier to reverse engineer that means we (by which I mean the people actually reverse engineering) can be pretty confident that there are no bugs because it is feasible to go over every line of code unlike other consoles. It also means that it is easier for Nintendo to maintain, small programs are easier to keep bug free than large ones.
Are there glitches present in the kernel? Certainly. But not every glitch can be exploited and the people who have the skills to reverse engineer the kernel have said that there are no exploitable glitches. Game save exploits won't help you either since games don't have the necessary privileges to modify the OS. On other systems like the 3DS whenever save game exploits were used they were either soley used for homebrew or they were chained with kernel exploits to modify the OS. Since there are no glitches in the kernel to exploit you can not chain them even if you had a game save exploit.
So what about glitches in the thing that loads the kernel? That would be the boot rom and bootloader. The boot rom has been completely reverse engineered, that's how we got Fusee Gelee. No one else has found any glitches that can be exploited in the boot rom using only software. There are other glitches but you need mod chips in order to actually use them. Stuff like the random timings to prevent fault injection not actually being random.
So what about the bootloader? That has also been entirely reverse engineered and the only exploitable bug was patched in firmware 6.2.0, not that that matters because it was impossible to use that bug anyway since it would take an ungodly amount of time to bruteforce the required data. The only other glitches can be exploited using mod chips, and in the case of the boot loader that's even worse than boot rom glitches since the boot loader can be patched in firmware updates unlike the boot rom.
There is definitely a way to hack any switch. It is called N private key used for code signing. If it will be leaked or "guessed" then there will be software hack.
I can't tell if you're shit posting here but guessing N's key is almost certainly not happening any time soon. Could it be leaked? I'm not sure. Brute forcing the key is definitely out of the question though. I'm not going to go in to the mathematics but if you're interested here is a blog post explaining why brute forcing AES with current computers is not going to happen.

Is it possible? Sure. But by the time it happens you'll be long dead. And yeah sure there's a 0.00000000001% chance that it could happen within your life time but ask any statistician and they'll tell you it's not happening.
Edit: Your only hope for a software exploit is if Nintendo hugely fucks up in a future update.
