I think Rust and Go have received that criticism also because they precisely "dared" to take an unconventional approach: Go is very opinionated and uses a radically simplified syntax without inheritance, exceptions and other things people are used to from other languages, which leads to many people trying to bend Go to their style of programming and getting frustrated; Rust has its focus on performance ("zero cost abstractions") and being memory safe without using GC, which leads to its famously steep learning curve. But I agree with OP: if you are going to start a new programming language today, you'd better try to bring some new ideas to the table, otherwise you're just crowding an already crowded space even more.
