> I wish we could get back to platforms (or OSes for that matter) focusing in reliability and stability

That's only a valid sentiment if you only use the big players. Both of those have medium/smaller competitors that have shown (for decades) that they are extremely boring, therefore stable.

Try convincing the CTO that this panoply of smaller players will be around for 5yrs or worth the effort migrating to.

I'm at a much smaller outfit now so we have more freedom but I'd dread to think the arguments I would've had at the 4000+ employee companies I was at before.
