I have a phd in physics (so I have at least some technical skill in this area) and find the QM sequence's argument for many worlds unconvincing.
Actually, attempting to steelman the QM Sequence made me realize that the objective collapse models are almost certainly wrong, due to the way they deal with the EPR correlations. So the sequence has been quite useful to me.
On the other hand, it also made me realize that the naive MWI is also almost certainly wrong, as it requires uncountable worlds created in any finite instance of time (unless I totally misunderstand the MWI version of radioactive decay, or any emission process for that matter). It has other issues, as well. Hence my current leanings toward some version of RQM, which EY seems to dislike almost as much as his straw Copenhagen, though for different reasons.
For me personally, the quantum sequence threw me into some doubt about the previous sequences I had read.
Right, I've had a similar experience, and I heard it voiced by others.
As a result of re-examining EY's take on epistemology of truth, I ended up drifting from the realist position (map vs territory) to an instrumentalist position (models vs inputs&outputs), but this is a topic for another thread. I am quite happy with the sequences related to cognitive science, where, admittedly, I have zero formal expertise. But they seem to match what the actual experts in the field say.
I am on the fence with the free-will "dissolution", precisely because I know that I am not qualified to spot an error and there is little else out there in terms of confirming evidence or testable predictions.
I am quite skeptical about the dangers of AGI x-risk, mainly because it seems to extrapolate too far beyond what is known into the fog of the unknown future, though do I appreciate quite a few points made in the relevant sequences. Again, I am not qualified to judge their validity.
as it (MWI) requires uncountable worlds created in any finite instance of time
How is that any more problematic than doing physics with real or complex numbers in the first place?

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
