I'm not sure. Part of the problem is that some of the biggest stakeholders have a vested interest in continuing the bot-voting status quo since that's their business model. Unless and until some big players agree that it's a problem it's hard to see how the ecosystem as a whole can change course.

From a different direction, maybe one idea would be to have another active SPS/DAO proposal that pays out to some trustworthy person who then uses those funds to bankroll not-yet-established developers to do some smaller, contained projects to help build developer capacity. That's using the coin to pay for services (software development) and potentially seeds some content (progress reports, developers talking shop with each other on-chain, etc.). IMO right now what limited development is happening is too duplicative (how many frontends do we need?) and big-project-focused (so there are fewer discrete "new things" for people to talk about or be excited about).
