carnegie science, seems like a contraadiction of words when you consider it was caregie was responsible for the destruction of john claude keelies labs and science in which his belief in aether was replaced by einsteins claim that space is a vacumn and light is a particle, now both debunked, and the return to wave theory

It has been reported that NASA is reconsidering going back to the SSME (RS-25) due to the recently discovered base heating problems from the SRBs. They will either need to do that or develop an RS-68 with a regeneratively cooled nozzle (RS-68R). Once you figure the cost of doing that versus the cost of a series produced RS-25, their isn't that big of a difference, plus the RS-25 will give you better isp.

Ares V was also planning to use SSMEs but is considering the cheaper and more modern RS-68s, wouldn't this also be a solution?

The SSME's in-stock will be depleted, and IIRC replaced with the RS-25's. NASA made a rule very early on to not use exclusively solid first stage.
Why build 2 different launch systems? It's far easier to build one.
The propellant depots are not NEEDED, but it's convenient.

Here comes an avalanche of bullshit.
No-one makes SSMEs. That's what you get from buying a warehouse full of them at the start of the program - the manufacturer closes up shop as soon as your orders stop. Restarting production now is not an option as all the parts are 1970s vintage. OTOH the solid motor modules are available *right now* from multiple suppliers.
Only 7m30s in he starts comparing apples to oranges.
19m20s in he explains 100mt launches would need propellant depots. FAIL.
