Jev vs. Laya: Bringing AI Decisions into Software

Structured decision models promise faster automation, but choosing between a managed API and open weights requires looking beyond headline benchmarks.

When I created Raspbian for the Raspberry Pi, I was excited to help bring low-cost compute into the hands of a next generation of tinkerers and programmers. However, I now despair that a Raspberry Pi can cost upwards of $300 because AI shortages are making personal computing unaffordable. Furthermore, bright young people are being discouraged from learning programming because they are being told it is now a commodity skill that AI will do. I have to ask myself what it was all for. Is this the future we were promised? If so, I'm starting to regret my part in it.

At its peak, Sun Microsystems was valued at 205B (394B if inflation adjusted). Sold software in enterprise servers. Got disrupted by Linux, x86, and commodity hardware. Ended up selling to Oracle for 7.4B, losing 96% of its value. Open source models running on local hardware can have a similar impact given what’s going on.

In this analysis, we explore CVE-2026-44706, a high-severity SQL injection (SQLi) vulnerability in Chatwoot. The flaw allows an attacker to execute arbitrary SQL commands against the application's database by exploiting unsanitized parameters controlled by a low-privilege user, paving the way for access to and exfiltration of sensitive data.
