Maybe it can do everything nowadays and more than the hardware, or just not as clean as hardware?
Not sure what you mean here, but if you're talking sound, digital is clean, precise, surgical, exact...all that. Some hardware can be the same, but the sought after hardware dulls things down a bit with distortion and other effects. So if you're going to use the DAW, you may find you need to compensate for that with mic choice, saturation plugins and eq. Some people love the ultra clean sound - and that's fine.
As kivetros mentioned, software can be easier to recall settings and managing your projects is definitely easier. But working with the software can be more challenging - finding that setting hidden in the menus - when you have no idea what it's even called can be rough. With hardware (aside from advanced synths and the like), you've got knobs and buttons which make operation simple. But then they do simple things - so it's appropriate. Maybe that's what you mean with clean - it's all laid in full sight, you're seeing the modules and the signal flow.
If you're absolutely not a computer person (probably not since you're here!) or don't need to spend any more time during the day - maybe the software isn't right for you. You can get a digital multi-track recorder for less than a computer, audio interface and software package from what I know.
On top of that, with a computer, you keep upgrading hardware, software and adding on plugins - the stuff can be a money pit, but I suppose it's also not mandatory to do so. It's just hard to resist with all the cool new stuff coming out all the time.
