Nested ellipse diagram with text

The following could serve as a place to start from:

\documentclass{article} 
\usepackage{amssymb} 
\usepackage{tikz} 
\usetikzlibrary{positioning,shapes}

\tikzset{set/.style={draw,ellipse,inner sep=0pt,align=left, anchor=east}}

\begin{document} 

\begin{tikzpicture}
\node[set,fill=blue!25,text width=8cm, minimum height=4cm] 
  (rea) {Artificial\\ Intelligence};
\node[set,fill=blue!50,text width=5cm, minimum height=3cm] 
 (int)  {Machine\\ Learning};
\node[set,fill=blue!75,text width=3cm, minimum height=2cm] 
  (nat)  {Deep\\ Learning};
\end{tikzpicture}

\end{document}

A PSTricks solution only for either fun or comparison purposes.

\documentclass[pstricks,border=12pt]{standalone}
\begin{document}
\begin{pspicture}[fillstyle=solid](16,10)
        \psellipse[fillcolor=red!20](8,5)(8,5)
        \psellipse[fillcolor=green!20](10,5)(6,4.25)
        \psellipse[fillcolor=blue!20](12,5)(4,3.25)
        \rput(2.5,5){\parbox{4cm}{\huge \textbf{\color{blue} Artificial Stupidity}}}
        \rput(6.5,5){\parbox{4cm}{\huge \textbf{\color{red} Deep Sleeping}}}

With a lot of patience it is possibile to built the diagrams using a tool that I like very much for your flexibility and creativity: Mathcha. I add my proposal here:
