All the tech jokes today remind me of the best I can remember from my good friend, Piotr. 7 years passed, did it age well? https://t.co/h6n1rPjG3l

Java is setting the standards for #AI infrastructure⚡
Benchmark of MCP server implementations across 4 major languages puts #MCP #Java & #SpringAI at the top of the performance charts: sub-ms latency, highest throughput, and the best CPU efficiency

Years later I found out it was PHP, not me <wink>, <wink>.

[Dariusz Jędrzejczyk @chemicL]

I am pretty sure I was vibe coding in early 2000s when I was pasting PHP snippets and randomly changing things hoping it'd finally work.

[Dariusz Jędrzejczyk @chemicL]

Nothing wrong with that and having fun. Although, worth noting, I did not manage to create anything usable or working.
