The first is an XKCD 605 (Extrapolating). The author makes bold predictions for the future as though they're inevitable, but gives zero evidence, because there is none, we're still at T=0. IBM is still in business. Wake me up when it's been taken out by someone vibe-designing a mainframe in kicad. Or even, let's see a dropbox clone get off the ground. Should be easy, right? (It's an HN tradition, after all.)
The second mistake is mistaking a large multiplier for infinity. The cost of code has not "collapsed to almost nothing" as the author claims. Talk to your CTO/CFO if you want the real story. They're probably freaking out over AI spend. But the point is, yes, AI has made things cheaper, but they didn't become monotonically zero.
AI had also raised the bar. You can't ship "good enough" anymore, it has to be great. And great still takes time. Time in QA, time obsessing over every workflow, time talking with customers and planning features.
Taste hasn't even entered the picture, and the analysis is already wrong.
