I thought real moat of software is requiring virtually no extensive knowledge/experience of both system and domain. Copying taste and network effect is significantly difficult. The fact is venture backed startups with plenty of talents and resources has been rarely making their positions in the market before vibe coding. That's why people at 20s can compete with experts in various areas. Current backlash is due to creation of guys with just x years experiences in the industry we often see in other mature enterprises.
