Wasting turns? That is silly, use a better harness. Also token usage can mitigated by incremental discovery instead of stuck 5k+ worth of tokens in the AGENT/Claude md file.
New? It stretches back industrially to the WS-* stuff in the early 00s (this is where the term originated), and on the academic side has roots in process calculi from the 90s and session types from the late 00s and early 10s.
They're referring to Enterprise customers, though should have been clear about it. Enterprise plans on Claude for example no longer include any baseline tokens. It's 100% usage based pricing.
True, but my friends in Enterprise still just purchase Claude Code subs and expense them. They basically get an allowance of $500 or so per month to buy various tools, and of course are banned from Chinese models. (Claude, Codex, Antigravity allowed, basically.)
And that's the real tl;dr. Hybrids win whenever anyone actually checks. To really be scientific we still have to check, but.. why wouldn't they? Probabilistic AI brings intuition/learning but can't plan/search. Classical brings planning and search, but has no intuition or learning.
Fortunately the economics of infinitely copyable software aren't going anywhere. If there is actually a sizable market, it can be served with relatively little cost, compared to hand-producing physical goods. I am not fully convinced there will be such a market, though.
