alt Hacker NewsI fully agree with everything you've said and think the Twitter one is a really good point that I haven't heard before.
That said, I think you've left out the impact of interest rates and the end of the Zero Interest Rate Policy (ZIRP) on this. So much of the "growth above all else", "revenue and user count matters more than profit" mindset companies had over the last 10 years was because ZIRP incentivizes them to invest in riskier assets. If safe investments pay 1% a year that's only a 10.4% return 10 years later. If safe investments pay 5% a year that's a 62.8% return 10 years later.
When rates are low, investors are more willing to focus on a company's potential because their money isn't making a lot while sitting in the bank. When rates went up (in addition to everything you said) investors all of a sudden wanted to see profit, not revenue or user base numbers which means a lot of these companies had to pivot their strategy fast. All the perks and crazy moonshot projects get cut and only things that are profitable or have a clear path to profitability are kept.
If you look back, that's exactly why we saw things like companies throwing crazy money at things like the metaverse and crypto and then practically over night pull the plug on them.
The charts below are the fed funds rate and the number of SWE jobs from Indeed, both from the fed and you can see how they align.
