With Apple’s latest announcement this device now has ~2 more years of updates from Apple before the device goes End of Life. This means no more security updates / bug fixes / etc will be released for this device. If you are looking for
a Chromebook an Apple laptop that will receive updates and support for several more years, this is not what you’re looking for.
Anything prior to 2017 will not be able to update to MacOS Ventura which was recently announced.
