Pretty clear and funny to me. Not sure how to explain it without just repeating the same thing.

It seems the markets will soon go through a period when Buffet's approach will work best, which makes it an inoportune moment for him to retire. Of course at his age retirement is expected, maybe even inevitable - that's the joke.

Just finding it mildly amusing to consider that in the messed up economics we are entering with Trump, there may be a shift to value investing, something I have always associated with Buffett.
