A mechanical lock vendor makes a mistake, one series of locks break or can be unlocked. Criminals still have to find them.
A "smart" lock vendor makes a mistake, all locks are unlocked or broken. Criminals can compromise them remotely, with full location available.

There are uses, for one "did i lock my door" 10 minutes after you drive away from home.
The problem is that the IT industry, as well noted by @Newk is in a state of constant "Move Fast/Break Things" MVP on a product that is dependent on internet connectivity, central management and power supply.
And the VAST majority of such companies fail within 5 years, or pivot to a new product leaving their old customers high and dry.
One should not be depending their daily access to their home on a developer having had their coffee, and a CEO not burning through the budget on partying and private jets.
