Context for Einstein's quote

[100c]

I'm interested in learning what Einstein thought of his own theories later in his life and came across the following quote.

"You imagine that I look back on my life's work with calm satisfaction. But from nearby it looks quite different. There is not a single concept of which I am convinced that it will stand firm, and I feel uncertain whether I am in general on the right track."
— Albert Einstein, on his 70th birthday, in a letter to Maurice Solovine, 28 March 1949 (in B. Hoffman Albert Einstein: Creator and Rebel 1972, p.328)

I'm just wondering if it was taken out of context or if he really did not believe in his own theories later in life. Anyone have a clue? Someone quoted that on a website trying to disprove relativity.

The C's say that Einstein found the solution to UFT. From Session 17 August 2000:

Q: (A) Okay. UFT. This is one of these things that I don't know what it is good for, because the Wave will erase everything and make everything new. Yet, it is in me, so let me ask. I don't know what it is good for, but I want to do it. Einstein was working on his UFT for like 30 years. Maybe more. He was changing his methods. At some point, did he realize that he found a solution? During all these thirty years, was there a point where he came upon the right solution?

A: Yes, but sadly, his solution for UFT largely erased TOR.

Q: (A) Once he found this solution, did he reject it because it erased TOR?

A: No. His progenitors sealed it, in order to keep intact the status quo.

I think relativity as it is now isn't correct, but I think Einstein's ideas and thought experiments are still valid, it's the mathematical description which needs work. So I think Einstein means exactly what he said in that quote.

Thanks Archaea!

The paradox's in relativity theory are contradictions with reality and disprove the theorem. I think he realized that later in his life.

I'm just trying to make sure I don't take that quote out of context because I want to reference it in my novel.
