The forever bigger approach is 'I made a hammer, my hammer hammers so well, I'll make a bigger hammer'. Someone asks 'what is the purpose of your hammer?'

The answer is 'we've found things we can do with it so we are sure that if we make a much larger one, we'll find something to do with it.'

Question gets asked 'but hammers are for nails, so you only need a hammer large enough to do nails, bigger nails, bigger hammers, but there's a limit to how big nails get.'

Answer is 'that's ok, we are sure that when we have a hammer bigger than any other hammer, someone will create a nail worthy of such a hammer.'

In a different camp someone says 'this hammer is rubbish at screws.'

Answer 'we'll make a small hammer specifically for screws. Trained on screws. Optimised for screws.'

World goes 'when it comes to screws, this little hammer is better than anything we've tried so far. In fact we'll call it a screwdriver given it was optimised for screws over nails'.

Bit like that. Use case should drive design, otherwise it is just very expensive guesswork.
