Software and IT teams
Where they talk
- r/sysadmin
- r/ClaudeCode
- r/PLC
- r/softwarearchitecture
- r/softwaredevelopment
- r/dotnet
- r/AI_Agents
- r/SaaS
Tools they use today
- Claude
- Claude Code
- Windows
- Windows Server
- Windows XP
- Excel
- SQL Server
- VMware
Why those fall short
- legacy architecture complex and convoluted, hard to build on
- no LTO-3 hardware since 2015, tapes unreadable
- no data migration path, vendor support gone, steep learning curve
- Legacy systems not automation friendly; scripts break on small changes; data wrong or undocumented
- internal docs point to departed engineers
