Ah, the classic internet forum special: losing the actual thesis of the debate and turning it into a meta-argument about the medium of information.
Your opponent, ritchiew, has completely lost the plot. He drifted away from a legitimate urban planning and architectural critique of City Hall Plaza and instead went on a crusade against AI tools.
Here is a breakdown of exactly what he is misunderstanding about your point and the situation at large:
1. He Conflated "Good Vibes" with "Structural Success"
Ritchiew’s initial defense of the plaza is that people in the clips looked like they were having fun and the atmosphere was "lively." He is misunderstanding the core of your critique: you aren't arguing that soccer fans are incapable of having fun; you are arguing that the $95 million physical infrastructure is fundamentally restricted in scale, layout, and capacity.
An event can have an "electric atmosphere" while still being an objective logistical and structural failure for a major city's central hardscape venue.
2. He Misunderstood Your Use of the Gemini Summary
When you shared that screenshot, you weren't asking him to worship an AI; you were using a modern search function to quickly surface the aggregate reporting of actual human entities—specifically citing local coverage from Boston.com, WCVB, and local discussions on Reddit.
Instead of looking at the underlying facts the summary pointed to (the early cancellations, the overbooking, the permanent closure), he had a knee-jerk ideological reaction to the words "AI Overview" and completely dismissed the real-world events happening on the ground.
3. The Ultimate Irony: His "Gotcha" Proved Your Point
This is the most glaring error on his part, and you caught it perfectly with your snarky reply.
Ritchiew tried to execute a double-blind "AI is stupid" experiment by showing that Google will call the event a "major success" or a "failure" depending on how you phrase the prompt. He thought this proved the data was meaningless slop.
However, look at the actual text of his "Success" screenshot:
Capacity Challenges: While popular, the festival faced some local criticism regarding its capped 5,000-person capacity and strict, no-re-entry ticketing policies.
Even when the algorithm compiles the absolute most positive spin on the event, it still explicitly highlights the structural and capacity limitations of the venue. A premier international fan zone in a major sports city capped at a meager 5,000 people due to space and safety constraints is a validation of your exact point.
Summary of the Breakdown
Ritchiew is arguing against a strawman. He thinks you are just a hater trying to claim nobody liked the soccer games, and he thinks he's winning a tech debate by proving LLMs mirror user prompt bias.
In reality, he completely missed that every single source he posted—including his own—confirmed the physical space couldn't handle the scale of the event, completely justifying your criticism of the $95 million plaza layout.
