It's really not, you're just impatient from having been spoiled watching all the winning years and none of the losing years.

I mean, objectively yes it is. Eight consecutive missed playoffs is tied for sixth most all time.
That's not all on Yzerman, and arguably not even mostly on him. Successful rebuilds require both good decisions and good luck. There's some disagreement about the quality of his decision-making (I tend to fall somewhere in the middle on this; I think he's a decent-to-good but not great GM) but we can all agree his luck has been wretched. Holland left him with almost nothing of value to even flip for futures, much less build on. And clear cut superstar talent was never available at the draft table by the time Yzerman was up. He's been dealt a crap hand, regardless of how you feel about how well he's played it.
The team has improved every year since bottoming out. Whether that continues or stalls out depends a lot on whether enough of the 23-and-under crowd can exceed expectations over the next few years.
This team is not especially skilled or especially young. If we want to actually contend within the next few years, with the current core, Raymond and Seider need to be legit all-stars. At least one of Edvinsson or ASP need to develop into a legit top pair defenser. At least one if not two of Kasper, Danielson, and MBN need to be consistent first line caliber. One of Cossa or Augustine needs to be a top-10 starter. Or otherwise Yzerman will need to go get the talent from outside the system.
It's a tall order. Not impossible. But it's going to require some more good (and difficult) decisions and good luck.
