but I produce the output of 3 or 4 2022 engineers and probably at better quality.

Possibly, but the output of a 2022 engineer is about 1/10th of the output of a 2010 engineer, so it's an extremely low bar.

also - as always with these claims there's no actual product / repo / whatever one could check.

I would love to see what these tools create but outside slop there's never: This works, is in production, here's the code.

Any day now.
