Yeah, I think "no more ZIRP" is a stand-in for "the economy is changing". And, that much is true. We just went through record-low rates for a record length of time, straight into the fastest hikes in history. That has repercussions, and I don't think anyone knows what they will be yet (oh and there are some interesting geopolitics as well).
But I can't help but think most of these layoffs are also a return to "normalcy". The pandemic job market was, literally, insane. But even before that, it was hard to get development work; prices were astronomical if you could even find people at all. For the tech ecosystem as a whole, there are advantages to salaries and wages coming down. That shifts around cui bono, but it allows for more ideas to see the light of day...maybe.
All this is to say I don't think it's doom and gloom. We'll have a period of transition and realignment, but tech skills will always be in demand.
