Indeed. Venus is probably more useful as a giant mine and laboratory. The same dynamics which stripped it of it hydrogen incidentally left it with a much higher than normal concentration of deuterium than we have on earth, and there are large quantities of organic elements like sulfur.
I remember Carl Sagan heading a team a few decades ago that was exploring bacteria to be released into the Venusian atmosphere which would process its carbon dioxide and sulfuric acid into something more useful (contained in those molecules you have hydrogen, oxygen, and sulfur! And there is also nitrogen already in the atmosphere, albeit in smaller quantities than here). I don't think much became of it, but that was decades ago before we properly understood genomes; it's possible that in future decades or centuries we will come up with a way to make such an organism.
With regards to the day, though, I read a plan for floating cities in the upper atmosphere which would be driven around the planet by winds at roughly the same speed as the Earth rotates, resulting in a more normal "day" for inhabitants. We could conceivably have a sort of "Cloud City" on Venus for mining deuterium/helium/sulfuric acid. And surface operations would be useful as well, if they ever became possible. Much larger quantities of tellurium, for example, which falls in pure form as snow at higher elevations.
