At Revolut, we treat products that are 99% complete as if they are closer to 0% done, emphasizing the importance of thoroughness and quality in product development.

The last 20% of a project often requires 80% of the work, emphasizing the importance of finishing and refining projects multiple times.

Be aware that after reaching 80-90% polish on a piece, you may experience diminishing returns in your practice, as perfection is not an achievable end point.

Paul Buchheit emphasizes the '90/10 solution', which means finding a way to achieve 90% of the benefit with only 10% of the work.

The threshold for effective quantum computing has improved to around 99% fidelity, meaning that if a quantum computer operates correctly 99% of the time, it can effectively manage errors and perform complex calculations.

The transition from 70% to 100% accuracy in AI applications is significant; users are willing to pay substantially more for reliable solutions that work consistently compared to those that only work part of the time.

The last 10% of detail in a presentation can make a significant difference in how a message is received and understood.

The last mile of achieving 100% accuracy is the hardest, often requiring human intervention to address inaccuracies in AI applications.

When 90 or 95% of all code is generated by AI, the human will still be in the loop; we shouldn't overstate the autonomy of AI.
