For what it’s worth, I worked for an insurance company 88-96 and was expert systems developer 001. Our expert system ran on PCs in our 30 branches then migrated to a mainframe. If you wanted serious reliability that was where it was at. Big blue. Anyway, I loved knowledge engineering, on call support and deep into it development (aionds). Captured $4 million in additional revenue as reported by the underwriting department. Ran for 6+ years total then I left) and then someone wanted “greater ROI”. They cut 1/3 of the underwriting staff. People I interviewed, took customer support calls from, learned about them as people, laughed with, etc. I didn’t feel so proud of my “accomplishments” afterwards. And anyone who thinks that rule-based expert systems, with all their flaws, were experimental-grade stuff, you haven’t taken a support call at 3am because YOUR hand crafted rule (about 1000 total) failed and it’s costing your employer money. Now we have deep neural nets that effectively are unexplainable (been there and feeling the pain).Consider the DARPA XAI retrospective report to back up my claim. What a long strange inference it’s been.
