Between 2023 and roughly 2025–2026, the LK‑99 episode will spur additional superconducting-materials research that produces new, distinct materials (not just LK‑99 variants) that are demonstrated in the literature as superconducting or strong candidates, with at least some being easier to manufacture or possessing superior properties to LK‑99 as originally claimed.
“I think this is going to unfold over the next couple of years with more material discovery, more invention coming off of this initial discovery and simulation model that then offers all these other opportunities for creating potentially new materials that maybe are easier to manufacture and better to produce.”

Explanation
Superconductor research activity did increase following the LK-99 episode, with continued materials-science interest in ambient-condition superconductivity, though no major new practical superconducting material distinct from and superior to LK-99 clearly emerged from this specific spark within the 2023-2026 window.
The question of whether LK‑99 itself is a true room‑temperature, ambient‑pressure superconductor that can be industrialized will not be definitively resolved immediately; it will take on the order of many months to a few years after August 2023 before there is broad scientific consensus one way or the other.
“Whether or not this actually does turn into a room temperature, superconducting material that can be industrialized and used in all these applications everyone's really excited about. I think it's probably months to years away from knowing”

Explanation
Scientific consensus that LK-99 was not a room-temperature superconductor formed within about a month of the initial claims (by September 2023), falling within Friedberg's predicted 'months to years' window.
Subsequent investigation of LK‑99 will conclude that it is not a practical room‑temperature superconductor but rather primarily a diamagnetic material, effectively becoming just another entry in the list of known diamagnetic/superconducting-at-low-temperature materials with no major technological impact.
“My intuition on this is that this is diamagnetic, and I think and I think we're going to find that, you know, it was it's like yet another material added to the list of materials and it's okay.”

Explanation
Subsequent replication attempts found LK-99's apparent levitation was due to ferromagnetic impurities and its resistance drop was attributed to a copper sulfide phase transition, not superconductivity, confirming it as diamagnetic/impure rather than a breakthrough material.
As of August 2023, a roughly 30% probability is an appropriate forecast that a preprint claiming room‑temperature, ambient‑pressure superconductivity in LK‑99 (or a very similar material) will be experimentally replicated to the satisfaction of the scientific community before the end of 2024.
“Yeah I think it's probably that's probably a good handicap for where we are.”

Explanation
LK-99 was not experimentally validated as a room-temperature superconductor by end of 2024; the scientific community broadly rejected the superconductivity claim within weeks of the original preprint.
Prominent economists Friedberg cites predict that U.S. long‑term interest rates (e.g., 10–30 year Treasuries) will settle in the 5–7% range and remain in that range for many years, constituting a new long‑run interest rate regime.
“there were two prominent economists who shared that they think we're going to be facing long term rates in the 5 to 7% range, very long term rates for a very long period of time that it is a new fiscal regime.”

Explanation
Long-term US Treasury yields did rise substantially from 2022 lows but did not settle into a sustained 5-7% range; the 10-year yield peaked briefly near 5% in October 2023 before falling back into the 4-4.5% range through 2024-2025.
No G8 country will return to sustained fiscal budget surpluses of the type seen in the U.S. during the Clinton administration; such surpluses will not recur in future decades.
“there's not going to be a single G8 country that all of a sudden moves away and starts printing surpluses. It happened almost as an accident, an aberration during the Clinton administration. It'll never happen again.”

Explanation
No G7/G8 country has returned to a sustained fiscal budget surplus since the Clinton-era US surplus; large structural deficits have persisted across major economies.
Absent major policy changes, U.S. federal budget deficits will continue to grow in absolute terms beyond 2023, remaining at or above roughly $1 trillion per year and trending higher over time.
“So the deficits are only going to get bigger and bigger.”

Explanation
US federal budget deficits have continued growing in absolute terms since 2023, remaining well above $1 trillion annually and trending higher through 2025.
If the U.S. continues to run large deficits and issues roughly $2 trillion of new Treasuries in late 2023, the 10‑year U.S. Treasury yield, then around 4.2%, will eventually rise into the 5–7% range.
“So what happens? Well, the bond rates go up and so the tenure goes up. Like Freeburg was saying from 4.2 to somewhere in the 5 to 7% range.”
View on YouTube
Explanation
The 10-year Treasury yield rose from around 4.2% but did not sustain a move into the 5-7% range; it peaked briefly near 5% in October 2023 before retreating.
If U.S. Treasury yields rise into the 5–7% range, equity discount rates will increase and broad U.S. stock market valuations will decline relative to prior levels.
“the discount rate on equities will go up. That means that the stock market relatively on a relative basis will go down.”

Explanation
Since Treasury yields did not sustain a move into the 5-7% range, the broader equity discount-rate and valuation decline this conditional predicted did not clearly materialize; US stock markets instead rallied substantially through 2024-2025.
If U.S. long‑term Treasury yields rise into the 5–7% range, the supply of risk capital (e.g., venture capital and private equity funding) will decline materially, leading to slower U.S. economic growth compared with the prior low‑rate decade.
“Risk risk will go down. And there'll be way less risk capital available for things like venture capital and private equity, just risk taking of all kinds. And so the economy will just grow slower.”

Explanation
Since long-term yields did not sustain a 5-7% range, the predicted decline in risk capital and slower economic growth did not clearly occur; venture funding and US GDP growth both improved through 2024-2025.
The approximately $2 trillion in additional U.S. Treasury bonds planned to be issued over the next two quarters (from mid‑2023) will find very strong investor demand and will be easily sold without difficulty in placing the issuance.
“this last 2 trillion, that'll be the easiest 2 trillion decide there will be a line out the door guaranteed.”

Explanation
The roughly $2 trillion in additional Treasury issuance in late 2023 was absorbed by the market without a failed auction, despite some temporary yield volatility around weaker individual auctions.
Given the current fiscal and monetary trajectory discussed (high debt levels, rising rates, global bond repricing), further inflationary pressure in the U.S. and other indebted Western economies is inevitable over the coming years.
“Coupled with inflation coupled with inflation. Right. Which is inevitable.”

Explanation
US inflation was not inevitable in the near term from this debt/rate trajectory; inflation actually declined substantially from its 2022 peak through 2023-2024 as the Fed's tightening took effect.
In the federal January 6th‑related criminal case brought by Special Counsel Jack Smith, Donald Trump may be convicted at trial in D.C. but will ultimately prevail on appeal, with the U.S. Supreme Court overturning the conviction on the grounds that the prosecution relied on an impermissibly novel legal theory.
“by the way, I think Trump is actually going to win this case. Maybe not in the D.C. jury pool, but I think he'll win it on appeal, because I just think... I think he has to take Supreme Court. He's going to win it because this is a novel legal theory.”
View on YouTube
Explanation
Trump's federal January 6th case never reached trial; the Supreme Court's July 2024 immunity ruling in Trump v. United States effectively shielded him from prosecution on official-acts grounds, and the case was ultimately dropped after his election win, achieving a similar practical outcome to what was predicted via a different legal mechanism than a post-conviction appeal reversal.
The continued criminal prosecutions of Donald Trump over January 6th will further polarize the U.S. electorate and significantly worsen political division over the next election cycle.
“this will tear the country apart.”

Explanation
The Trump prosecutions were a significant and divisive feature of the 2024 election cycle, though attributing a clear, isolated worsening of political division specifically to them versus other factors is difficult to establish.
The 2024 U.S. presidential election will primarily center on disputes over the 2020 election and the Trump prosecutions, rather than on forward‑looking policy issues.
“This is what 2024 is not going to be about.”

Explanation
The 2024 election was not primarily about the 2020 election or the Trump prosecutions; it centered heavily on the economy, inflation, and immigration as the dominant issues.
