When was it decided that it was the users responsibility to use the latest version of a web browser (regardless of how inconvenient it is for the user)? Oh right, Google and the cabal that runs the web decided so. Just because something is "old" doesn't mean it is obsolete. This mentality is very wrong, and needs to be opposed. It isn't helping the users, it is helping the platforms. Up until a few years ago, it was the responsibility of the developer to gracefully fall back and support as many users as possible. Now, instead, we design under the assumption that everyone has a computer made within the last 12-18 months, with the latest updates, on a high speed, low latency connection. And that is awful, because it is cutting out users who aren't privileged enough to afford the web. The new "improved" Google Voice is utter trash. It makes my 2011 Macbook grind to a halt. And for what? So that it cosmetically resembles their new phone app. And most tech reporting websites are gushing about how it looks. And what is the justification for all of this garbage? Is the web faster? more reliable? More accessible to people with disabilities? NO.
