Without going into details, basically the reason comes down to the fact they are tiny and the star is too bright in comparison. Without a coronagraph which can block the starlight even the most powerful telescopes (like JWST) we've built can't image them.
Amidst this, just let me try to give my own experience with language while working in a field where it doesn't have much traction (scientific/numerical programming). A couple of years ago, after being tired trying to make Python faster, I was looking for a language to write simulation code in. Fortran (and C/C++) has been the go-to choice in my field for decades but I wanted to try a modern language. I tried Julia but the workflow didn't come naturally to me. Also by default, it also wasn't ahead-of-time compilable. Rust was my second choice but it's type system/design, expressiveness and tooling (rust-analyzer) won me over. I have written so much of it and I really enjoy writing it. Borrow checker isn't really an issue 99% of time when writing scientific code. And when it is (self-referential data structures), you can just use an arena (or something equivalent). The C/Fortran inter-op is great so it's still so easy for me to build my own abstractions on top for the more general stuff like solving ODEs and sparse matrices.
And of course, there is speed, memory safety and ability to parallelize things so effortlessly (rayon is magical), but I feel those were never the things that actually won me over. The language was just a joy to write.
To those who feel on the contrary, I would genuinely like to understand why average consumer won't be priced out of hardware? The silicon industry is already quite centralised. Everywhere we already see the concept of ownership disappearing.
It's quite difficult for me to visualise a non-dystopian future where our PCs are just mere screens and every compute happens on a remote cloud, owned by some corporation, charging you subscription fees to even add and multiply numbers.
I would be the happiest if this (perhaps the most) pessimistic scenario doesn't pan out, but I can't deny that it feels like that's where we are heading.
The reason I like Zotero is because I can use it offline, have my all documents synced (the backup feature is one of the best things) when needed and I can organize my papers according to project/paper I'm working on. Actually one thing I do wish Zotero would add is tab groups which will allow me have papers open but grouped by project. It's based on Firefox which does support this so I hope it's a matter of time.
The companies trying to make these plans are just looking for money. It's not for some noble goal for progress. If you fail to see that, I'm sorry for you.
When is it enough?
For those who don't know, only PDS 70b and c are the exoplanets directly imaged which are still embedded inside thier nascent protoplanetary disk. For most other planets, the disk gas has mostly been cleared/dissipated/accreted.
For those who are more interested you can refer to the detection papers for both:
