<p>Looks like Ubuntu 18.04lts will get hardware updates almost until mid 2020. Maintenance updates until 2023 and security updates until 2028 : <a href="https://ubuntu.com/about/release-cycle">https://ubuntu.com/about/release-cycle</a> I don't see any reason personally not to stay with 18.04lts for a while. Who knows what a couple years might bring.</p>

<div style="font-family: trebuchet ms,sans-serif;">I suspect it is lazy development teams using legacy/32 bit code to save time/money. IE ain't broke, dont need to change, Leave it. When I was doing system integration in 2006/2008 there were still people using TSX32 and looking for compatible hardware because they didn't want to recode for another OS.</div>

<div>Its actually more complicated than just lazy development teams, but it is a significant part of it.</div>
<div> </div>
<div>(Note, when I say 32-bit I am referring to x86, and 64-bit I am referring to amd64. ARM-based hardware is a different topic altogether)</div>
<div> </div>
<div>From a hardware perspective, virtually everything made in the last 15 years is 64-bit, save for some Atom-based netbooks (do people still use these?). From that perspective it makes sense to drop 32-bit ISOs, as very little hardware still in use will need it. If you need a 32-bit OS, there are other distros besides Ubuntu that will continue to exist (Debian, Gentoo, Arch Linux 32, and the like). At least in the US, it is impossible to buy a brand new PC today that is NOT 64-bit.</div>
<div> </div>
<div>That said, this isn't about hardware. This is about software, and running 32-bit software in a 64-bit environment.</div>
<div> </div>
<div>A lot of legacy software was written, compiled, and released in 32-bit and not 64-bit, and has no chance of ever being ported to 64-bit. This is especially the case with older games. To run this software in 64-bit environments will require 32-bit libraries to make it work.</div>
<div> </div>
<div>A lot of *modern* software (software released within the last year or so) is also written and compiled in 32-bit, despite compilers allowing 64-bit support with a single button. A lot of modern middleware and software engines ONLY support 32-bit builds. Many device drivers (like Brother printer drivers) are 32-bit only, or depend on 32-bit libraries to function correctly (Nvidia drivers). Why *these* developers refuse to enter the 64-bit era is beyond me.</div>
<div> </div>
<div>What you can't deny is that, until now, shipping a 32-bit binary will reach the maximum audience possible.</div>
<div> </div>
<div>What the folks at Canonical are doing is removing the 32-bit compatibility libraries from the Ubuntu repos from Ubuntu 19.10 onwards, thus preventing future 64-bit Ubuntu installs from running 32-bit software at all. They are asking users to find other solutions.</div>
<div> </div>
<div>Hope this clears things up.</div>
<div> </div>
<div>(For open source software, this is mostly a non-issue, of course)</div>
