I'm not counting cumulative hours of productive work, I'm counting duration from inception to working implementation.
I consider one person knocking something out in one day that would previously have taken them 10 days of wrestling with to be a 10x increase in productivity.
And I'd consider one person building a proof of concept in a couple hours that would have taken 5 people 10 weeks of back and forth meetings, planning, pushback and reluctance to be a 1000x improvement in productivity.
These tools are seriously reducing the bar for knocking stuff out that would have previously required much more significant time investment and risk to even consider let alone tackle.
I've personally used copilot and chatgpt to implement things that would have taken me months of study and wrestling with in just a few hours.
Tell me you're not an engineer without telling me you're not an engineer
