Yes, but sometimes a human isn't the best 'thing' to do that. Humans make mistakes, and perhaps having a system that will alert the controller when he tries to clear an aircraft for take off when there's someone crossing it ahead of them is a good idea, or alert the controller when he tries to instruct an aircraft to route along a taxiway behind an aircraft to which he has just given a pushback clearance.
We have had TCAS for years.
Flight decks used to have navigators, flight engineers, wireless operators as well as pilots.
Would we really trust a human to monitor the thousands of parameters and data points of modern turbofan operation without any assistance, rather than multiple onboard computers, not forgetting the myriad computers back at Derby or the other real-time ops centres of the engine manufacturers doing the same thing?
And regardless of the safety nets etc, you can't deny that having a radar-like label being projected on to the window, or having an IR-augmented view, would help in LVP. That's the sort of thing digital tower tech can do.

Interesting that one of the medical requirements to be the holder of an ATCO licence is a pair of serviceable eyeballs, to provide stereoscopic vision and depth perception. In contrast, the remote tower camera system is essentially monocular.

It sounds like a real nightmare. What is the advantage? Also, I haven't found out what "IR" means. See what getting old does.

So you don't have to keep switching from the window, to A-SMGCS (GMR), to EFPS (electronic strips), and back again.
So you could perhaps have a visual indication through colour or symbol to represent confirmation that a pushback manoeuvre had begun, especially if the aircraft is parked end on to you, or perhaps round the back in the old Sierras, or at the bottom of the old Victors, which you can't see from the tower.
So you could see each aircraft's target take off time as you look out of the window to help you decide who gives way to whom, instead of looking at your strips.
So you can see aircraft type of something nearly two miles away in the dark as you're giving a conditional clearance on it to someone else withouit having to look down at your strips.
So you could have a visual indication of the aircraft being ready for taxi (having received such a request by data link) without the aircraft actually calling up on the R/T.
So you could see the position of aircraft beneath you, under the floor of the VCR, and check relative speeds, which is not so easy on A-SMGCS.
Apologies for the lack of order of those, that's just off the top of my head in a few minutes.
All those seem useful to me.

Maybe surprisingly, not often. You were used to the systems you had & you just got on with it. That's how it was. Mis-indents could occur , but I didn't witness many of them. PRI only was good experience. Later, we all got used to SSR & Code Callsign Conversion but it was revealing to see that those controllers who didn't have PRI only experience found it very difficult, during TRUCE PRI only exercises, to continue to provide radar service without SSR; & even without CCC.

A similar story repeats with every generation of new tools.
I trained at LHR without A-SMGCS where every aircraft has identity, and inbounds have parking stand. In the old tower the secondary failed for a week or so, those who had only ever known controlling with it struggled, those who knew ops before it was introduced took a session to get back into the swing of things.
Now it is so integral to operations that we would consider putting flow restrictions on if it failed in the same way.
Same with electronic strips. As those of us used to using paper strips at LHR become the minority, paper strips is no longer considered an appropriate fallback mode.
This, of course, puts more stringent requirements on resilience for those pieces of kit.

Yes, Gonzo. What you say is so very true, & understandable. But, it is a pity that the "old tools" cannot be resurrected in these sort of circumstances.
Off on a tangent; I well remember the use of Climb & Descend VMC. This was a very useful tool when Radar was not available. We used it a lot at Aberdeen in the days before Radar (& even after Radar became available - when it failed for days on end !). Mostly worked a treat; although, I can remember one or two embarrassing events !
Climb/Descend a 1000 ft. above/below other traffic was very useful too; & even in a Radar environment, when pushed.

Mis-indents could occur ,
My slightly facetious point entirely - "not often" and "could occur" = did occur = occurred too often.

'Digital ATC'........Hmm
"What goes around, comes around"
I remember listening to CDs, back in 1986.........'Digital Audio',.... While doing my area course at CATC.
It was 'The future'......All the Hi-Fi shows said so.
Have you sen how many analogue vinyl LPs J.Sainsbury is selling these days?
