Chinese Banking revolution - Use of big data and artificial-intelligence technology to give loans to Small Businesses

Chinese Banking revolution - Use of big data and artificial-intelligence technology to give loans to Small Businesses:

https://economictimes.indiatimes.com/news/international/business/jack-mas-290-billion-loan-machine-is-changing-chinese-banking/articleshow/70418197.cms

Excerpts:
One uniquely Chinese source of information for banks is the government-administered social credit system, which is being tested in cities across the country as a way to reward good deeds and punish misbehavior. In one potential scenario cited by MYbank President Jin Xiaolong in a recent interview, a small-business owner whose social credit score dropped because he failed to return a borrowed umbrella would find it harder to get a loan.

But the biggest data trove may come from payments providers like the one operated by Ma’s Ant Financial, the biggest shareholder of MYbank. After obtaining authorization from borrowers, MYbank analyzes real-time transactions to gain insights into creditworthiness. For example, a drop in customer payments at a retailer’s flagship store might be an early indicator that the company’s prospects -- and its ability to repay debt -- are deteriorating.

The upshot of more information is a loan approval rate at MYbank that’s four times higher than at traditional lenders, which typically reject 80% of small-business loan requests and take at least 30 days to process applications, according to Jin, who plans to double MYbank’s roster of borrowers in three years. He said the Hangzhou-based firm’s operating cost per loan is about 3 yuan, versus 2,000 yuan at traditional rivals.

Yes silver bullet by Mark Seemann

Excerpts:

So it is with technology improvements. Automated testing is available, but not ubiquitous. Git is free, but still organisations stick to suboptimal version control. Haskell and F# are mature languages, yet programmers still program in C# or Java.

....

If you accept my argument, that order-of-magnitude improvements appeared after 1986, this implies that Brooks' premise was wrong. In that case, there's no reason to believe that we've seen the last significant improvement to software development.

I think that more such improvements await us. I suggest that statically typed functional programming offers such an advance, but if history teaches us anything, it seems that breakthroughs tend to be unpredictable.
