I think the future of indiehacking is barbell shaped.
On the right, build AI things for AI people. It will get cloned to shit. Some will work, many will not. Fastest execution plus distribution wins. Be prepared to make tons of money one month and nothing the next.
On the left, build boring things that nobody wants to clone, that will take years to gain enough market share. Slow burn. CRM for Chihuahua owners. Newsletter tool for bakeries. Hyper niche.
Everything in the middle is a dead zone now.
