2 technologies you can’t ignore:Javascript and blockchain

I don’t know a single experienced developer working with blockchain to be honest.

You can totally ignore blockchain. For 99.99% of use cases, a boring SQL database will be simpler and cheaper, if less "sexy".

Blockchains require two conditions to be the superior choice:

1. Must be decentralized. This is where most use cases fail. Even when multiple parties come together, it's frequently preferable to create a third-party to administer their agreed-upon tech for many reasons: compliance, governance, error recovery, cost, efficiency, etc.
2. Participants must be adversarial. If everyone is cooperating, then you would use a distributed consensus algorithm like Raft/Paxos.

A currency beyond the obvious control of governments fits the bill; almost everything else doesn't.

hard pass

The key for JS is at what point to START ignoring it.

For eg, you learn ES5, some React. Do you decide to also start writing your backend in JS and learn Node? Or do you pick a more general-purpose language like Python? This has been on my mind a lot lately.

Nice. Good call and totally agree. JS is by far the most popular programming language in the world

According to the Devskiller IT Skills and Hiring Report 2020, 72% of companies are looking to hire JavaScript experts. Enter the search term “JavaScript” on job site Indeed and you’ll find over 40,000 jobs requiring this skill (in the US). Run the same search on LinkedIn and the results are in excess of 125,000.
