The debates
Aadhaar and privacy
Critics said a central biometric database invites surveillance and profiling. In 2017 security researcher Anand Venkatanarayanan disputed his claims on biometric safety and savings point by point. In 2018 the Supreme Court upheld Aadhaar but struck down Section 57. Private companies could no longer make it mandatory.
He said he had no evidence that Aadhaar was made for surveillance. He called some concerns disingenuous. He said the minimal data collected was privacy by design and he backed a strong data protection law. After the verdict he said Aadhaar had “undergone the ultimate scrutiny” and debate had made it stronger.

Exclusion from welfare
Economist Reetika Khera linked at least 25 hunger deaths to people who could not draw rations without Aadhaar authentication. Activists said fingerprint failures hit the old and manual workers hardest. The government denied any Aadhaar-related starvation deaths. The Supreme Court allowed Aadhaar for welfare and noted the state’s assurance that no one would be denied rights for lacking it.
He pointed to Andhra Pradesh where he said proper design and a manual override gave full inclusion. He has said “Aadhaar includes, it doesn’t exclude.” No direct reply from him to Khera’s death count was found.

The 2014 Lok Sabha run
He left UIDAI to contest Bangalore South for the Congress. He was reported as the richest candidate of 2014 with declared assets of ₹7,710 crore. His rival Ananth Kumar said he was committing hara-kiri. He lost by 228,575 votes in a BJP sweep.
He conceded on counting day and said he would continue his social work. In 2019 he said: “Standing for elections was a big mistake I have learnt in life.” He has not been active in politics since. He has since worked with the Modi government on payments and exam reform.

Should India build its own AI models?
In January 2025 he said India’s goal should not be to build one more large language model. Perplexity CEO Aravind Srinivas replied that it was “essential to do both”. He said Nilekani was wrong to push Indians to ignore model-training skills.
No direct reply to Srinivas was found. In July 2025 he told Rest of World that models will become common and India should not get obsessed with them. He funds AI4Bharat to build open Indian-language models. He says the work is to make AI useful to people.

Can technology fix government?
Reviewers questioned his faith in tech-led reform. Publishers Weekly said Imagining India would frustrate readers who put equity and sustainability first. Mihir S. Sharma wrote that Rebooting India sidelined the problems of adoption. He called its reliance on a supportive prime minister “the common fantasy”.
No direct reply to these reviews was found. Rebooting India argues that a small skilled team with political backing can deliver at scale. He cites Aadhaar and UPI as proof that India can diffuse technology to a billion people.
