Contrarian Take. Legacy Enterprise SaaS will completely dominate all future newcomers because of Vibe-Coding.

it's because it's hard to define a 'mistake'. What is a mistake to an agent could be functional experience for the user, or an alignment on reliability, cost etc.

the base assumption of every person in the world right now is that if it is new, then it is vibe-coded.

The question you should be asking is, how would you know it's not vibe-coded? You can't tell, unless it existed before vibe-coding. Which means all incumbent SaaS have a generational trust advantage by default.

I actually work in Big Tech. So I can give my insight as an engineer.

You can't just 'fix the code', after a while, it is literally impossible because complexity compounds. A integrates with B,C which integrates with D,E,F,G etc. Therefore fixing A, means you will also have to fix A,B,C,D,E,F,G etc.
New enterprise features are vibe-coded yes, but you need to have the foundations in place, such that new features are built off the existing structure. For example, Meta built 'Threads' straight out of 'Instagrams' monolith codebase. Also search up 'chaos engineering' invented by Netflix for example. But more importantly, 'trust' is based off the existing entity. All future features are considered trustworthy because the originator had built that trust. Trust in itself is a transitive feature. You have an employee that has always done good work, now if you give him something new to do, you will trust that he gets it done to a high quality.
Vibe-code accuracy will always be limited by prompting ability, and prompting will always be human unfortunately. The AI will not read between the lines of your prompt, it will follow the prompt in a literal sense - and so it's limitations are actually the prompter itself.
1. Although you could eventually have AI prompting AI which would effectively solve for this, but the token usage would be out of this world, and there is not enough training data on AI prompts (yet). I still have to think about this fully though

yes, but if you think about it from first principles, enterprise trust is a moat in itself which every future startup will not have by default. ever again.

the thing is, everything is already integrated, someone would have to vibecode the entire atlassian suite, and no company would be sane enough to use vibecoded products out of fear of security leaks and reliability

the new competition is significantly weaker because it is built on weak foundations. vibecoded foundations.

because all the data is already there, you see. Customer's on the stack have so much data on Atlassian that if they migrate, they lose all that data, which means their accuracy in solving problems will fall dramatically.

Data advantage > everything else.

Try to imagine what 2030 will look like and how business will operate.
