  • It’s so basic that documentation is completely unnecessary.

    “De-duping” could mean multiple things, depending on what you mean by “duplicate”.

    It could mean that the entire row of some table is the same. But that has nothing to do with the kind of fraud he’s talking about. Two people with the same SSN but different names wouldn’t be duplicates by that definition, so “de-duping” wouldn’t remove it.

    It can also mean that a certain value shows up more than once (eg just the SSN). But that’s something you often want in database systems. A transaction log of SSN contributions would likely have that SSN repeated hundreds of times. It has nothing to do with fraud, it’s just how you record that the same account has multiple contributions.

    A database system as large as the SSA has needs to deal with all kinds of variations in data (misspellings, abbreviations, moves, siblings, common names, etc). Something as simplistic as “no dupes anywhere” would break immediately.


  • I’d broaden that to a whole host of “green” and “alternative energy” sectors.

    All the panic about Chinese “overproduction” of EVs and similar technologies is just China going whole hog on those industries. It’s not an “overproduction” in the traditional sense, where a company produces more than the market will bear and has to sell excess inventory at a loss. China just produces all of this stuff cheaply and at a huge scale.

    About 20 years ago the general perception was that EVs were a joke https://www.youtube.com/watch?v=X2HX5wsQVEA Now we have cost effective solar and wind, efficient battery storage, good and cheap EVs and drones, modern heat pumps etc.

    I don’t even think all the tariffs will matter in the long run. China is currently adopting all that stuff at a breakneck pace. Their production capacity won’t just go away once they’ve saturated the domestic market and the growing number of countries that have trade agreements with China). At that point, Chinese manufacturers will have no choice but to start actually selling below cost, just so they can clear inventory.

    And this has a snowball effect too. Energy is often the limiting factor in production. An abundance of cheap energy makes it cheaper to produce more cheap energy production.
