Vibe coding in my opinion is analogous to say borrowing on a credit card to gamble on a startup.

Occasionally, in IRL you hear the feel good story how Fred smith gambled the last $5,000 to save FedEx and so on, but most people with that mindset end up crashing out.

Vibe coding a product runs the risk of acquiring too much tech debt before project is successful.

Product Market Fit is very hard, you need to keep enough room for pivots. Changes in direction will always accumulate debt, even when tech is well written. It is far more difficult when you accumulate debt quickly.

The counterpoint being that procrastinating and over-engineering prematurely or building lot of unrelated tooling and loosing focus can also bring the product down quickly or never let it start .

Being able to vibe code POCs etc is a great tool if done in a controlled limited well defined way.

Just as borrowing cash on your credit card is not always bad, it just usually is.
