Gotta be careful with long term predictions. Otherwise you end up really wrong, like Intel's promise of 10GHz by 2005 running at < 1 volt.
Yup, that actually happened, and that statement was only 5 years prior in 2000.
TSMC's too fast roadmap not going as planned, I could have never predicted that. Some 3nm products have been delayed also. TSMC did too much posturing towards investors and customers to inflate their importance and solidify contracts. Meanwhile Nvidia has turned to Intel for some products.
Massive legal implications though. Researchers have demonstrated how easy it is to correlate that supposed anonymous marketing data with an actual person. Scam operations are even buying customer data because corporations will sell to anyone. Then there's potential for abuse in politics and law...
With the way people use technology today it will likely accelerate. US consumers have already set the zero privacy standard. Nissan and Kia even sell data on driver's "bedroom activities" as they indicate in the privacy policies.
