> I think that's why individual contributors in big teams aren't seeing massive benefits from AI where a small team or solo developer may be seeing greater leverage.

This rings true. It is the best time ever for small teams. A big team is potentially several smaller teams, so this can be a force multiplier for them too.

Another force multiplier for reorganizing larger teams, be willing to consider smaller teams starting with single contributors.

What this is the worst time for: slow adaptation.
