BD, It's all spin.
What is the point in EFD, EFPS, iTEC, SESAR et al.
Allegedly, at this time, several of the airfields in my local TMA (and probably yours), don't even have the benefit of code-callsign conversion.
This means that controllers working in adjacent areas of (often very complex) airspace, are not even looking at the same radar picture!
For decades, (given the fragmented state of the UK ATC 'system'), the only reason that the unthinkable hasn't happened is due to the skill and professionalism of those working in these often under-equipped control rooms.
Let's get back to basics.
Let's get everyone singing from the same hynm-sheet. (sorry if this sounds like the management yuck-speak I so utterly detest).
Then, and only then, can we start talking about the future, because at this time, it appears we still haven't got the present working properly.
