>Actually surpassing the guy you're cheating off of is a lot harder
That's true and what you're describing is called Second Mover Advantage.
It's easier to catch up than innovate, so China can reach to where US is now pretty quickly. US has moved on by then but the distance to catch up again is smaller so they catch up again faster.
Essentially, China is getting two steps closer to US while US is getting one step further away, eventually they're roughly at the same spot and China has to choose between staying one step behind US while they invent stuff, or trying to invent new stuff and compete with them.
Do they want to follow USA on a guide-led tour of arms or run alongside them in an arms race?
Reality is that these aren't mutually exclusive and China is attempting to do both; steal everything, innovate when they can and hopefully pull ahead at least a little.

>The planform is ripped directly from American studies into low observability designs from the mid 90s
Do you know if any of those went beyond wind tunnel/RCS mock-ups?
It feels like putting one in the air and possibly into production counts as innovation at this point, there's an awful lot of work involved in going from a stolen/public design to a flying air craft.
