I would argue the opposite..

What you get right now is mass replicated software, just another copy of sap/office/Spotify/whatever

That software is not made individually for you, you get a copy like millions of other people and there is nearly no market anymore for individual software.

Llms might change that, we have a bunch of internal apps now for small annoying things..

They all have there quirks, but are only accessible internally and make life a little bit easier for people working for us.

Most of them are one shot llms things, throw away if you do not need it anymore or just one shoot again

The question is whether that's a good thing or not; software adages like "Not Invented Here" aren't going to go away. For personal tools / experiments it's probably fine, just like hacking together something in your spare time, but it can become a risk if you, others, or a business start to depend on it (just like spare time hacked tools).

I'd argue that in most cases it's better to do some research and find out if a tool already exists, and if it isn't exactly how you want it... to get used to it, like one did with all other tools they used.
