They had 1 tower with 1 operator and no redundancy at a fairly busy airport, which is definitely concerning.
Doing something to distribute information differently could result in redundancy such that if the commercial craft have a 1-3 mile ADS-B view around them, they can check that ATC isn't giving them bad instructions and that others are following directions.
Why couldn't it be? We need fewer ATC than we need pilots, by a long shot. The actual requested new hires for ATC is in the range of 2k (with 1k expected to stay on staff).
With roughly a 120k salary, and assuming all 2k stay on-board that's what, an additional $200mil needed to fully fund?
Meanwhile, the airline industry had a $30b net profit, so it doesn't look like this is even something that'd bankrupt the industry if we taxed them to cover the costs of ATC. It's a 1% tax that's needed.
Even with a super duper fancy modernized system, we'd still want towers staffed sufficiently. Having just 1 person there is a problem even if everything is super modernized. When an issue comes up that the system can't or isn't handling well that's 1 person to make all the calls. Hopefully 2 things aren't happening and hopefully they don't need or want a second opinion.
As for hiring competent people, the DC metro has 6.3 million people. I find it really hard to believe there's not 3 more in the area that could handle being an ATC operator.
And it's not like we don't already have 99% of the existing buildings, infrastructure, and computers already setup. It's literally just the personnel that's lacking.
They might be capable, but why would they want to?
"Why couldn't it be?"
Things like coordination and communication in high traffic environments don't scale well. Finding efficiencies in the procedures and systems can eliminate potential miscommunication and missed handoffs.

Actually only some airports have been upgraded while others are waiting. Do you think another person would have prevented this incident? From the recordings and facts so far, it doesn't seem like it.
in this case it seems like it could definitely have been solved by tech. both aircraft were traveling at predictable paths and opertating nominally.
You could argue that helicopters, being very nimble craft, should have ADS-B receivers and provide display and sound their own collision warnings to their pilots. That's perfectly possible, I just don't think it's mandated
