Better design enabling rowhammer, meltdown, and the like... But when it comes to failures I would bet things must have improved when you measure failure per operation. Computers did not fail often 30 years ago. If they failed orders of magnitudes more nowadays we would definitely notice. I have absolutely no numbers on reliability in any kind of metric.
