Hiker, software engineer (primarily C++, Java, and Python), Minecraft modder, hunter (of the Hunt Showdown variety), biker, adoptive Akronite, and general doer of assorted things.
Eh… Without examples, I don’t know that this is a good warning.
Everyone gets into different technologies at their own pace. Even if it does bite OP in some abstract way because they eventually get to some complex use case, that’s okay; it’s all a learning experience.
One thing I’ve learned since becoming a home owner ~5 years ago… There’s a lot of stuff on the Internet that tries to get you to a point of hysteria.

This is the kind of stair step crack you need to worry about. It’s a big gap, many blocks, etc. It’s a sign part of your foundation is sinking.
What you have is a block missing some mortar and a crack below (which can happen if water gets into the block … which happens when you’re missing mortar). You can have someone look at it, but I think an honest contractor would tell you “get it repointed or do it yourself, keep an eye on it.”
That just looks like weathering. I have some similar cracks (… that I really do need to get to sooner or later…), it just needs repointed to prevent further water intrusion (take out the old mortar and put new mortar in).
I would not bother your insurance company with this.
Yeah, that could definitely be cool.
Cost would be a big factor … Fandom got big by being free and eventually replaced (or heavily customized) mediawiki to the point it’s unrecognizable.
