Did it have all the hype and momentum, though? It was pretty widely viewed as a low- to negative-value addition, and honestly when I see someone on here talking about how useless AI is for coding, I assume they were tainted by Github copilot and never bothered updating their priors.

My first experience was with cursor and my entire team went through a honeymoon period before it got kind of sidelined. Average usage was giving an agent a couple shots at a problem but usually solving it ourselves ultimately. Internal demos were lackluster. Team was firmware though so might not be a great topic for GenAI yet.

just my experience of course, but it had a lot of hype. It got into a lot of people's workflow and really had a strong first mover advantage. The fact that they supported neovim as a first-class editor surely helped a ton. But then they released their next set of features without neovim support and only (IIRC) support VS Code. That took a lot of wind out of the sails. Then combined with them for some reason being on older models (or with thinking turned down or whatever), the results got less and less useful. If Co-pilot had made their agent stuff work with neovim and with a CLI, I think they'd be the clear leader.
