Jira and Linear are legacy software

Theo (t3.gg) argues that issue trackers are dead and that Linear’s agent-native pivot points toward prototype-first development replacing spec-driven workflows.

• Coding agents are active in 75%+ of Linear enterprise workspaces; agent-completed work volume grew 5x in the last 3 months.
• Agents authored nearly 25% of new Linear issues — AI is now opening tickets, not just closing them.
• Atlassian acquired The Browser Company, which Theo reads as confirmation Jira is not seriously thinking about AI-era dev workflows.
• GitHub has zero shared leadership between product and engineering orgs, which Theo cites as a structural reason GitHub is deteriorating.
• Jira’s ToS historically banned sharing performance benchmarks; Theo says Jira dashboards at Twitch took over 2 minutes to load.
• Linear’s new launches: an AI agent, a Skills product for codifying repeated workflows, and Automations for scheduled/triggered agent tasks.
• Theo’s thesis: build a throwaway prototype first, write the spec after — half the time the prototype ships as-is; pre-build specs are almost always inaccurate.
