It's not really that. The quality of these tools will probably increase, and I'm fine with more competition, and with less experienced developers being empowered to build their own products.
What is depressing to me is that the products showcased here are essentially cookie-cutter derivatives built on and around the AI hype cycle. They're barely UI wrappers around LLMs marketed as something groundbreaking. So the thought of the web being flooded with these kinds of sites, in addition to the increase in spam and other AI generated content, is just depressing.
