What's with all these new accelerators in Southeast Asia? Do we really need them?

This year alone we’re seeing so many new accelerators launch in SEA, particularly Singapore. It feels like a case of deja vu again, cos back when JFDI launched, there was a similar wave? And guess what, most of these accelerators died out. Now we’re seeing another wave, with folks like muru-d, MaGIC Accelerator Program, Rockstart, and l337 Ventures all doing their thing. I’m really skeptical if these guys are adding value to the ecosystem. I don’t see all the top startups at the moment (Grabtaxi, Tokopedia) coming out of these accelerators, so will startups succeed because of accelerators, or in spite of them?
