Lisps have multiple issues, but syntax is definitely not it. It might take a little bit of time getting used to, if you are coming from another language, but LISPs are some of the most readable languages I've ever worked with.

That is an opinion framed as a fact. There's plenty to rub a coder the wrong way, such as the sigil in builtin functions like @import, the dot syntax in structures (.{}, Timestamp{ .seconds = 0, .nanos = 0, };), triple slash comments (///), and multiline strings (beginning each with \\ - good luck grepping for escaped backslashes). However, that is just like any programming language - none is immune to this criticism.
