Technology experts say healing what ails the Healthcare.gov website will be a tougher task than the Obama administration acknowledges. "It's going to cost a lot of tax dollars to get this done," says Bill Curtis, senior vice president and chief scientist at CAST, a French software analysis company with offices in the U.S. Curtis says programmers and systems analysts start fixing troubled websites by addressing the glitches they can see. But based on his analysis of the site, he believes the ongoing repairs are likely to reveal even deeper problems, making it tough to predict when all the site's issues will be resolved.
