Are you using a 42 year old book to find flaws in my argumentation? Let's talk real, contemporary numbers.

NuBank: from ~12M customers in 2019, grown to 25M in a year, then to 48M at IPO a year later, then to 114M in 2024, to 131M in 2025 - 991.67% growth within 6 years and still going. Not in theory, not conceptually, not because "SICP has told them". They did get-the-shit-done. Not acknowledging that Datomic and Clojure has something to do with this succes would be simply a dishonest gesture.

Walmart - the canonical "Clojure at scale" story. The eReceipts system processed every purchase across 5,000+ US stores plus online/mobile, built and maintained by just 8 developers. Architect Anthony Marcar's line after Black Friday: the system "handled its first Walmart Black Friday and came out without a scratch". They cited 5-10x less code than alternatives.

Apple - known for using Lisp for a long time.

Metabase - open-source BI. ~46k GitHub stars.

Amperity - customer data platform, "99% Clojure" - their own quote.

Netflix - been using Clojure since forever. Watch their talk from the last year's Conj. It's eye-opening on stability of complex systems.

Cisco - malware analysis platform. Multiple huge Clojure projects: IROH - Incident Response Orchestration Hub, CTIM/CTIA - Cisco Threat Intelligence Model and API, etc.

Braintree/PayPal - payments backend. CircleCI. Grammarly (this guys are on SBCL)

And that's just a short list of actual, real, profitable businesses built with and maintained using Lisp. I don't know what "SICP has told" you, but maybe you just need to look around, things have changed a bit since then.
