This latest emacs upgrade has been seamless and hasn't required any cognitive overhead to transition.
That said, I'll always be back to IntelliJ for heavy edits. There's nothing better for Java.
I find for less structured languages the less-structured approach engendered by emacs is an advantage.
The fact that TRAMP lets you open files on remote systems in and of itself is fairly mundane. What makes it really cool is that it works seamlessly also with dual-pane dired, and just about anything you do in Emacs. It turns remote filesystems into local ones.
Being able to, in my regular file manager (I like Sunrise Commander), treat any combination of remote and local filesystems as though they were local, is a huge productivity boost.
Not affiliated, just getting good use out of it.

BBEdit - launched in 1992 (26 years ago), still around.
Notepad++ - launched in 2003 (15 years ago), still around.
Textmate - launched in 2004 (14 years ago), still around.
Sublime - launched in 2008 (10 years ago), still around.
Almost all the mainstream editors since 1995 at least are around. They have been marginalized, but they're generally around. Especially cross platform editors and even more so Open Source ones have great survival characteristics.
That's why both Atom and VS Code seem like solid long term bets.
Clark Maurer still updates Slickedit at least annually though.
A bit of digging around:
Brief seems completely dead, was killed off by Borland.
Multiedit seems operational: http://multieditsoftware.com/ It doesn't seem to active, but you can still buy the product.
Semware is still technically "alive": http://www.semware.com/ It was last updated in 2005, so there's that :)
Slickedit: is definitely operational: https://www.slickedit.com/ I have no idea why you're counting it as dead?
Epsilon: seems operational http://www.lugaru.com/ They even had a release in 2018.
To also clarify my previous statement, in the history of software, there's pre-mass PC and pre-internet. In my opinion the 2 periods are not comparable. Anything which was launched before 1995-9 or so is way more likely to have died. The mass PC and the internet have offered even commercial products much higher resilience.
Now, if a tool for developers reaches the mainstream, it super likely to stick.
I find very often that arguments by Emacs and Vim users come from a time before 1999 or so, when companies were super volatile. Look at this: https://www.joelonsoftware.com/2003/08/01/rick-chapman-is-in...
>One major reason for me to use Emacs and not newer software is that it is not only cross-platform but also gives some confidence that I will be able to use it in twenty years from now on a new platform.
You're ignoring the first half of the sentence:
BBEdit - not on Linux
Notepad++ - not cross platform
Textmate - not cross platform
Sublime - cross platform - but can I see the source? If not, I have little faith it will be around in 20 years.
My (heavily customized) Emacs environment on Windows gives me the same experience as in Linux. No warts at all.
There's even good native editors if you want that, Scite comes to mind.
Anyway, my point was just don't dismiss out of hand, don't belittle other people. Of course, if you're happy with Emacs, continue to be happy.
Oh, and the irony of this is me railing against Emacs/Vim when I'm also a Vim user and have been for at least 10 years. I say also because I've been using VS Code quite a bit lately.
Actually though pre-6.6 QNX had a great GUI and is capable of running on desktops and laptops just fine¹. I rather like it.
¹ Hardware support is not great but way better than you might be expecting. Either way, it runs fine in VMWare and VirtualBox. I'm currently trying to acquire some parts to build a PowerPC laptop for QNX.
One major reason for me to use Emacs and not newer software is that it is not only cross-platform but also gives some confidence that I will be able to use it in twenty years from now on a new platform. The same could be said about Vim. In comparison to these two, newer editors sometimes appear too ephemeral and fragile to me. (Then again, I used to use BBedit on the Mac and just found out that it's still around! What a nice surprise!)
