If anything, the enormous amount of social media attention on AI has made it easier to raise VC in other trending areas because all of the low-quality "me too" startups have gotten pulled into the fashionable AI orbit. This has significantly improved the signal-to-noise ratio in these non-AI areas because the legions of trend-jumping founders are all doing AI, the startups that remain tend to be founded by people with substantial investment and expertise in their domain without regard for fashion. This is good for VCs and for founders.
