Re. 
Well, yes and no. Noticed your reply via e-mail notification. 
Things slowed down with regards to keyboards for me—except maybe my typing speed. I’m kinda happy with the keyboards I use as daily drivers: a Rama U80 with Kailh Box Jades and MT3 profile keycaps at home (albeit the Rama drama—still waiting for my third U80 
) and a black Tex Shura with Cherry MX Silent Red switches (see below) at work, which replaced an aging Tex Yoda II.
Also the pandemic made me skip most meetups (a local indoor one last year and before that just outdoor ones at hacker camps) and the amount of keyboards I built in the past feels also rather low albeit it actually weren’t that few:
-
A Cyberpunk 2077/Araska themed Kbdfans D45 which arrived last October, but I only found appropriate keycaps a few months ago:
I currently have it connected to the PlayStation—where I also play Cyberpunk 2077.
-
And two Tex Shuras with metal top cases (a black one with a normal cursor cross and red one with a 6-key cursor block) this April.
-
Bought a Kiser Monorail (V4N4G0N compatible) in March this year second hand on the Fediverse. Was totally happy about the offer as I missed the V4N4G0N groupbuy back then. It just cried for GMK Laser to get a cyberdeck-ish appearance:
(Figured I shouldn’t talk about new keyboards without posting pictures, even if it might be off-topic in this thread. But at least two of the pictures are kinda on-topic as the keyboards have haptically separated cursor blocks. 
)
And there’s currently only one keyboard I’m waiting for: The PolyKbd with tiny screens in each key. And I still have at least half a dozen unbuilt kits at home, including e.g. a Zlant XL, i.e. a 5-row Zlant.
For me the n+1 rule feels currently more present with bicycles, albeit nothing like all the shiny road bikes seen in the Fun Between your Legs! (Cycling Thread) thread: I recently bought a Skatebike (think unicycle with a skateboard truck in front) of unknown make and a Strida Mk1 folding bicycle, both at least 30 years old. Might revive that thread with posting some pictures of them there.
Indeed, love that Ghostbusters theme despite not all keycaps fit perfectly. (I think the left Control is too narrow.) Those industrial style keycaps (spacebar and cursor keys) work very well with the Ghostbuster artisan.
